SEASONAL INGREDIENT: Winter Veg

We're still suffering through winter weather (yes, snow in New York City today, people!). But the cold outside doesn't mean we can't enjoy some wonderful produce -- and specifically, winter vegetables -- indoors in our kitchens. There's beauty in their variety of flavor but also in their shapes, sizes, colors, and uses. It's never been easier to "eat the rainbow" of colors in vegetables alone, and many of these items are hearty enough to make into a soup, to pair with the rich meat stews of the season, or to skip the meat altogether and enjoy these gifts of nature on their own as a substantial, diet- and environment-friendly alternative to animal proteins. Below are some great options, as well as some ideas as to what to do with these wonderful winter veggies:

- Radicchio tardivo: This elegant, elongated variety of radicchio di Treviso comes from northeastern Italy around the town of Treviso in the Veneto. It has slim leaves that are white and tipped with burgundy, a result of a second "forced" growth process when the harvested heads are placed in growing tanks with flowing water for a second growth; they're then harvested late (hence "tardivo"). Their crisp, bitter leaves are a thing of beauty, and work especially well in dishes of the area, like a risotto or pasta with radicchio, gorgonzola, and walnuts. This veg is great grilled, or oven-roasted with a little balsamic and a sprinkling of sugar to take away the bitter edge. It's also great in a winter salad with endive and perhaps some kale or watercress.

- Celery root, or Celeriac: This is quite literally the root of celery, but as a root vegetable it's got a bit of starch to it. You can slice into matchsticks to enjoy raw in a salad, or cook it with a potato or two to make a healthier, lower-carb version of mashed potatoes
(trick: the lack of gluten in the celeriac makes its substitution for mashed taters a great healthy upgrade, and you can put it in a food processor for a smooth puree without the gummy mess of potatoes alone). This also means it makes a fabulous soup -- it's great comfort food in cold weather, especially with some fried leeks and a drizzle of maple syrup on top.

- Cauliflower: Much has been made lately of the previously-lowly, pale head of cauliflower, and with good reason. This pallid cruciferous vegetable is actually really healthy for us, and is incredibly versatile. Cook the florets as is traditional and you can toss them with pasta, pine nuts, and raisins in olive oil with a splash of wine and you have a great pasta dish, Sicilian in origin. Pulse in a food processor and you have gluten-free couscous. Roast whole in the oven rubbed with olive oil, salt, and spices, and you have an excellent main course meat stand-in (You can also slice the cauliflower into "steaks" and serve vegetarian versions of steak preparations: cauliflower au poivre, anyone?).

- Broccolo romano, or Romanesco: This is what Romans refer to simply as a "broccolo" -- they think the dark green version that is our standard is "broccolo siciliano" (Sicilian broccoli). This is a popular side dish in Rome, cooked until meltingly tender in olive oil, with garlic and peperoncino. Mammamia! It's also tossed with pasta, and served in the disappearing-but-traditional Roman soup, broccoli ed arzilla made with stingray and roman broccoli in broth -- really delicious.

- Winter squash: This family includes butternut, spaghetti, acorn, delicata, and on and on. Roasted with just a drizzle of olive oil, a few cloves of garlic, and a sprinkling of sea salt, winter squash are healthful and a great substitute for potatoes alongside proteins. They can be pureed into amazing soups. They can be roasted alongside other vegetables. They can become filling for pastas like ravioli. Spaghetti squash can be served like its namesake pasta, in place of the pasta itself! And delicata squash can be served skin-on, for extra ease in prep...and extra fiber. These nubby veggies are versatile and amazingly delicious, and even the seeds should be saved, cleaned, and roasted to make into a healthy snack, to sprinkle on salads, to grind into a pesto...even to candy for dessert!

- Brussels sprouts: These mini-cabbages named after a Northern European city (still a mystery) have caught on again since the "new" century, and have become a ubiquitous side dish in restaurants from Manhattan to Minneapolis. And good for them! Because they're very good for us, another cruciferous veggie full of fiber and vitamins. I make mine with pancetta, shallots, balsamic or sherry vinegar, and a touch of honey -- and they're a perennial Thanksgiving favorite.

- Cabbage: Big brother to the brussels sprouts above, cabbage is another healthful, incredibly versatile veg. There are many varieties, including regular green or white cabbage, red cabbage, and savoy cabbage with its slightly curlier, thinner leaves. Cabbage can be shredded and eaten raw, as in cole slaw, or cooked, as in stewed cabbage (I like mine sweet-and-sour, like they make it in central Europe, stewed with some vinegar, salt and sugar). It can be fermented and transformed into kimchi, or simply eaten as part of a salad. It can be stuffed with ground meat or vegetables and stewed for stuffed cabbage or other savory packets or spring rolls. It's also great in a simple soup with a veggie broth, brightened with the acidity of a splash of vinegar. 

- Beets: Another underdog root veggie we root for (food pun!), the beet was and is still "having a moment" on menus across America. These former outcasts have experienced a renaissance, and I'm happy about that, because they're gorgeous and packed full of vitamins and antioxidants, and they make a great soup (borscht), a great salad ingredient, and a great side dish.

They're a substitute for the deep ruby color of raw beef, so vegan tartares now have new life. They can be golden or fuchsia or swirly candy-cane colored (chioggia beets), they can be sliced thinly or fried into chips or served julienned in a salad with lots of carrots and pistachios and fresh herbs and warm spices like cumin and ras-el-hanout...They pair really well with those carrots, but also with goat cheese and ricotta cheese, with nuts and herbs, they're great dressed with vinegars or with sweet-sour pomegranate molasses or silan date syrup for a Middle Eastern-North African vibe, and they're great in Central and Eastern European preparations, with dill and meat and potatoes and flaky smoked fish...they're as versatile as they are pretty, and as inexpensive health powerhouses, they can't be...well, you know...

Enjoy the healthy vegetable variety that comes with the winter season, and get your fill while you can!

RECIPE: Ribollita (Tuscan minestrone bread soup)

There are few things better on a bitter cold day, or evening, than a bowl of ribollita, the cool weather Tuscan bread soup. It's made with a Tuscan minestrone base, to which stale bread is added -- preferably the tasteless, salt-free crusty bread that became a staple in Tuscany when an overwhelming majority of citizens refused to pay a steep salt tax. It's even been used to clean precious frescoes in Tuscan churches, as its texture is similar to a sponge (its stand-alone taste is fairly similar, too). 

How is a Tuscan minestrone different from your average minestrone, you may ask? It shares all of the basic vegetables, like celery, carrots, and onions, of course. But Tuscans, like their mangiafagioli (bean-eaters) moniker suggests, often add cannellini beans to dishes, for added heft, starch, and protein.

Their minestrone is no exception, so they use beans to replace the tiny pasta tubes that the rest of the Italian peninsula uses. They also add Tuscan kale (or lacinato), what in Italian is called cavolo nero (black kale) or cavolo laciniato (fringed kale). This is sliced or hand-torn into strips that get thrown into the minestrone, adding color and great nutrients and fiber to the soup. 

The thing that turns Tuscan minestrone into ribollita (which literally means "re-boiled") is the addition of bread. The Tuscans are a thrifty bunch, not ones to let bread go to waste simply because it's stale. So they have a series of bread-thickened soups in their culinary repertoire to make the most of it. Ribollita is the wintry version, and it's one of my all-time favorites. It freezes well, so you can make a huge pot of it during, say, a February snowstorm. You can eat it until (and if) you get sick of it, and freeze the rest for another blustery night.

RIBOLLITA

(Serves 4-8)

6 TBS. Olive oil, plus more for drizzling

1 onion, chopped into medium dice

1 carrot, chopped into medium dice

2 stalks celery, chopped into medium dice

3 cloves garlic

2 cups cooked or canned cannellini beans, drained

4 whole peeled tomatoes or 1 15-oz. can peeled tomatoes

8 cups vegetable stock or chicken stock

1 sprig fresh rosemary

2 sprigs fresh thyme

2 bunches chopped cavolo nero (black kale)

1 small loaf Tuscan (unsalted) or crusty peasant bread, preferably a day old

1/2 cup freshly grated parmigiano cheese

Salt & pepper to taste

- Warm 6 TBS. of olive oil in a large pot over medium heat. When it's hot, toss in the onion, celery, carrot, and garlic. Sprinkle with a dash of salt and pepper and cook, stirring so the vegetables don't stick, until they're softened, about 5 minutes.

- Add the tomatoes and beans, stir and cook for 2 minutes. Add the broth and the rosemary and thyme, and cook for 15-20 minutes, so the flavors meld.

- Add the kale (and remove the herbs if you'd like), and stir to blend. Add salt and pepper to taste.

- Tearing the bread with your hands into bite-sized chunks, slowly add the bread to the broth, mixing to absorb the bread every 10 pieces or so. You may not use the whole loaf, but you may. The consistency should be a thick porridge. Let the soup cook another 15 minutes or so, simmering on low, so the bread breaks down and becomes integrated into the soup a bit. Taste to adjust for seasoning.

- To serve, ladle into bowls, drizzle generously with the highest-quality extra-virgin olive oil you can find (Tuscan is most relevant here), and sprinkle with grated parmigiano cheese.

Note: Like most soups, this one is even better the next day, or even the day after that. Since it's ribollita (re-boiled) anyway, it keeps very well for several days in the fridge, or for 2 months in the freezer.

RECIPE: Zuppa di Cavolo Verde con i Ceci e Pomodori

I've always considered March to be an unpleasant month. In the northeastern U.S., and particularly in New York City, it's still pretty much winter. It could rain or sleet, we could get bombarded by a blizzard, or we could wake up to a lovely, short-lived spring morning. But mostly, it's gray and cold. Tonight, it's chilly and rainy and windy, and it's Sunday. It's a perfect evening for a warming, and healthy, bowl of homemade soup. Italian-style, ovviamente.

This soup is something I made with 3 things in mind:

1. I wanted the soup to be a meal-in-a-bowl, and healthy.

2. I wanted to use the organic kale I'd bought at the market, which I purchased also in the interest of healthy eating.

3. I wanted to utilize pantry staples so the soup could be easily reproduced and made on a budget of very little -- and when you don't feel like braving the weather outside.

So, here you have it. Of course, it's even better if you soak and cook your own chickpeas, and if you have fresh tomatoes in season. But since it's March, and I'm a realist, I'll pick my battles and encourage you only to make your own stock. It's easy, it's inexpensive, and it makes your kitchen -- your whole apartment or house, really -- smell like home. 

Zuppa di Cavolo Verde con i Ceci e Pomodori

1 small onion, finely chopped

4 stalks of celery, finely diced

4 carrots, peeled and finely diced

2 TBSP. extra-virgin olive oil

1/4 cup dry white wine

10 cups chicken or vegetable stock (homemade is best)

1 small can (14 oz.) chopped San Marzano tomatoes

1/2 teaspoon dried chili flakes

1 small can (14 oz.) chickpeas, drained from liquid and rinsed under water

1 head of kale (cavolo verde), or Tuscan cavolo nero if available, washed and dried

salt & pepper, to taste

- In a large soup pot, heat the olive oil until warm, and then add the onion, celery, and carrot. Saute on medium-low until onions are translucent, about 5 minutes.

- Add the white wine to the vegetables, and turn the heat up to medium until most of the liquid is cooked off.

- Add the stock and cover until it comes to a boil.

- Add the tomatoes and chili flakes, cover, and cook for approximately 10 minutes.

- Add the chickpeas, lower the heat to medium-low, cover, and continue cooking.

- With a sharp knife, cut the base of the head of kale off, remove any thick veins, and then slice through the leaves, horizontally, cutting the kale into strips about 1/4 inch wide, so the kale leaves become a sort of "confetti."

- Add the kale to the soup (the leaves will wilt). Stir, and continue to cook for another 15 minutes, allowing flavors to blend. Taste for seasoning, and add salt and pepper to taste.

* This soup, like most soups, is best served the day after it's made, allowing the flavors to develop and blend overnight.
