WHY IT’S LIGHT For beefy taste without excess fat, use ground sirloin instead of chuck. This chili is also bulked up with extra portions of beans and tomatoes. Briefly cooking the cocoa, chili powder, and tomato paste before adding the beef helps intensify their flavors.

WHY IT’S LIGHT Low-fat yogurt, garlic, and vinegar are combined in a creamy, tangy dressing—without a drop of oil. Walnuts roasted with the vegetables add satisfying crunch and not much fat.

WHY IT’S LIGHT Using light mayonnaise (and a bit of water) in the dressing considerably reduces the calories and fat. Lime juice and chili powder contribute unexpected flavor notes while still keeping the whole thing light.

Salty sautéed peppers, especially those that are mildly hot, are delicious summer treats—irresistible bites with a glass of chilled wine.

This is a tangy, creamy, and herbaceous version of a classic dressing that is well paired with crisp and sturdy romaine lettuce. Use whole uncut leaves; if the heads are large, you may need to remove many of the outer leaves to get to the pale green sweet leaves at the heart. Little Gem and Winter Density are small tender varieties that are perfect for this dressing and for Caesar salad.

For Bryant, shucking and eating freshly picked ears of corn reminds him how for generations his family was intimately connected with their food sources—they ate what they grew. When you eat juicy corn on the cob, served straight from the pot and slathered with butter, it’s easy to imagine such a connection. Freshness really matters with corn—as soon as it is picked, the sugars in the corn start converting to starch. Choose ears that feel plump and fat with tightly closed, bright green husks and golden brown silks. Look for stems that are moist and pale green, and check for tight, small, plump kernels. Kernels cut from the cob offer other possibilities: sautéed, with sweet peppers, chiles, tomatoes, squash, or beans; or used in cornbread and griddle cakes, and in numerous soups and salsas. To prepare kernels for cooking, pull off the husks and cornsilk from the ears of corn. Rub the ears with a clean dish towel to remove any clinging cornsilk, and snap off the stems. Cut the kernels from the cobs: Hold an ear by the tip, stand it up vertically with the stem end down, and use a sharp knife to cut down the length of the cob, cutting just deep enough to slice off the kernels. This is messy; to contain the kernels, it helps to work in a large bowl, or on a small cutting board set inside a roasting pan.

Steaming is one of the simplest and most nutritious ways to cook vegetables. It is an especially good method to capture the delicate flavors of tender young vegetables such as turnips and turnip greens, carrots and carrot tops, peas and pea shoots, green beans, cauliflower, beets, and spinach. After cooking, the vegetables can be seasoned lightly with salt and perhaps a squeeze of lemon juice, or flavored with various vinegars, olive oil or butter, or a sauce.

Oliver likes to blanch his greens. Blanching vegetables means cooking them briefly in rapidly boiling water. Blanching is suitable for all sorts of leafy greens: chard, kale, beet greens, turnip tops, collards, cabbage, spinach, sea purslane, dandelion, and nettles. Blanched greens can be seasoned and served warm; chopped and added to stuffings, meatballs, soups, and stews; or dressed and served cold or at room temperature.

Leafy greens of all sorts are good simply wilted, cooked by a combination of steaming and sautéing. Tender greens such as spinach, watercress, and pea shoots cook quickly, in just a few minutes, uncovered. The sturdier greens (chard, kale, broccoli rabe, collards, cabbage, amaranth, beet greens, turnip tops) take longer. These are best cut into ribbons, or shreds, and covered to steam during cooking. It helps to have a large shallow pan that can accommodate a big mound of leaves at the outset, a tight-fitting lid, and a pair of tongs to stir and lift the greens to keep them moving and cooking evenly.

I make this soup year-round with fresh shell beans in the summer and fall, and with dried beans in the winter. The other vegetables in the soup vary with the season. It can be put together quickly if the beans are already cooked.

Dirty rice is a spicy Cajun dish typically made with sausage, chicken giblets, and vegetables—the meats color the rice and make it look “dirty.” There are as many versions of the dish as there are cooks. This one, contributed by Tanya Holland of Brown Sugar Kitchen, in Oakland, California, is spicy, light, and meatless.

This dish of Lidia’s is what I make for supper when I return home tired and hungry after traveling. I like it very plain, with lots of parsley, but you could spice it up by adding a pinch of dried chile flakes or chopped anchovy, and serving it with grated cheese.

Charlie makes this refreshing soup when tomatoes are at their peak of ripeness and flavor. The same method can be applied to extract flavor from other watery vegetables and fruits, such as cucumber and watermelon.

I like an uncomplicated tomato sauce that tastes of sweet, flavorful tomatoes, garlic, and chile. It makes a delicious pasta sauce by itself, or it can be garnished with fresh herbs and cheese, and it can be the base of many other sauces.

The simplest guacamole is made with avocado, onions, jalapeño, lime, salt, and cilantro. The amounts of the ingredients can vary; guacamole is very forgiving. The important things are to taste for a balance of salt, heat, and acid and to make the guacamole taste the way you like it.

This is a salad that David Chang (page 80) made in the Green Kitchen. David’s cooking often applies traditional Asian flavorings and methods to the foods of this continent. This salad is similar to a tomato and mozzarella salad, but it is quite different and surprising in its combination of flavors.

Sweet corn comes in an array of yellows and whites. There are ears that are full of white kernels, yellow kernels, or both yellow and white. The open-pollinated varieties begin to lose sweetness, converting sugar to starch from the moment they are picked. Modern hybrids have been bred to keep their sweetness for a few days, but some argue that these varieties are too sweet and lack “corn flavor.” What better way to decide than by experimenting with a few varieties to discover your own favorites? No matter the variety, corn is still best eaten fresh, the day it’s picked. Look at the cut end to gauge the freshness. Select ears that are plump, juicy, and bright in color, with a fresh cut. The brown silk may look a little sticky on a very fresh ear of corn. Don’t be put off if there is a worm at the tip—not that one wishes for a worm, but its presence is a healthy sign that the farmer is not using pesticides. If you can’t eat it immediately, store corn in the refrigerator, unhusked. Shuck corn right before you cook it, removing the husk and all the silk. If there has been a worm visitor, slice off the evidence; no harm has been done to the rest of the ear. To remove the kernels from the cob, hold onto the stem end, pointing the tip of the ear down, and run your knife down the cob, cutting off the kernels. The trick is to gauge the right depth at which to cut—not so deep as to take some of the cob with the kernel, but not so shallow that too much of the kernel is left behind. It is less messy if you tip your ear into a roasting pan to catch all the kernels as they are shaved off. If you wish, rub the cob with the back of the knife to remove all the corn milk from the kernel bits left behind.
