Here we take the elements of a vegetarian lasagna filling--ricotta, spinach and Parmesan cheese--and nestle them into roasted portobello mushroom caps. The recipe works best with very large portobello caps; if you can only find smaller ones, buy one or two extra and divide the filling among all the caps. Serve with a tossed salad and a whole-wheat dinner roll or spaghetti tossed with marinara sauce.
Easy cleanup: Recipes that require cooking spray can leave behind a sticky residue that can be hard to clean. To save time and keep your baking sheet looking fresh, line it with a layer of foil before you apply the cooking spray.
