With just 15 calories per cup, mushrooms are a hungry dieter’s dream food, and they’re easy to incorporate into recipes. For a simple side dish, quarter a large container of white or crimini mushrooms, drizzle with a little lower-sodium soy sauce, and roast at 400 degrees until the veggies are soft and browned. Or, top a bunless turkey burger or grilled chicken breast with a mound of sautéed ‘shrooms — it’s easy to skip the bread when you have a yummy, high-volume topping to gobble up. You can even use mushrooms to create a low-cal, low-carb “pizza”: layer a roasted or grilled Portobello cap with marinara sauce and a sprinkling of shredded part-skim mozzarella cheese, and broil until the cheese is melted.
