The Italian classic is given a gourmet touch with this frittata. Savory eggs are married with Swiss, Mozzarella, Cheddar, and Parmesan cheeses, for a dish that is light, fluffy, and deliciously rich. It makes a great breakfast or brunch for a crowd, or even a light luncheon dish. Simply wonderful. Two 1.4 lb. trays, each serves 4-6.
