Nutritional yeast (aka “nooch”) has been a star in the health foods universe for generations. Rich in B vitamins, selenium, and zinc, this deactivated (nonrising) yeast boasts a delightfully cheesy flavor; it’s also gluten free, dairy free, and a complete protein. A boon for vegetarians: Nutritional yeast is often fortified with vitamin B12, typically lacking in plant foods. Look for the yellow flakes or powder prepackaged or in bulk sections. Don’t confuse it with brewer’s yeast, a beer-making byproduct with a less-appealing taste.

Breakfast. Sauté chopped spinach leaves in a little olive oil until wilted, top with a poached or scrambled egg, and sprinkle with nutritional yeast.

Lunch. In a blender, whirl 1 tablespoon nutritional yeast, ¼ cup olive oil,
2 tablespoons fresh lemon juice, and ½ teaspoon Italian herb seasoning. Drizzle over a Mediterranean salad of romaine lettuce, red bell pepper, black olives, and avocado (add flaked tuna or salmon if desired).

Dinner. Stir a tablespoon of nutritional yeast into any soup, stew, or casserole to boost flavor; fold into mashed potatoes or grain dishes, too.

Snack. Sprinkle nutritional yeast directly onto hot popcorn.
