An ingredient nearly as beefy as meat, portobello mushrooms are hearty, earthy vegetables that can be roasted, grilled, sautéed and more. Once you break off their stems, portobello mushroom caps are roughly the same size and shape of the average pancake, and can hold their form when cooked. This durability means that they are often treated like meat patties. Paula features them in her Portobello Mushroom Burger, finished with a pesto mayonnaise and peppery arugula.

Food Network Magazine’s stuffed mushroom (pictured above) boasts a filling of vitamin-rich spinach, fresh tomato and pecorino and mozzarella cheeses. After the caps are quickly broiled, they are topped with the spinach mixture and creamy ricotta cheese, and are cooked again until the stuffing is warm. Serve each mushroom with a refreshing celery salad for a quick but satisfying weeknight dinner.
