Pat fillets dry with paper towels then dip into beaten egg. In a shallow wide bowl, combine Parmesan cheese, flour, cornmeal, salt, and pepper. Dredge fillets in dry mixer to coat well. Place a slice of American cheese on each flounder fillet then roll up, securing with a toothpick. Place in a baking dish and drizzle with melted butter. Bake at 350° for about 20 minutes, or until fish flakes with a fork.
If desired, serve with a quick and easy cheese sauce. Heat milk and American cheese over low heat, stirring frequently, until sauce is smooth.
