2 lbs. hamburger
1 1/2 c. seasoned bread crumbs (variation: you can substitute any of the new varieties of tiny pasta, shells, elbows, etc for the bread crumbs)
2 eggs
2 c. spaghetti sauce (homemade or bottled)
6 slices of American cheese

Combine hamburger, bread crumbs and eggs; mix well. Add 1 1/2 cup of spaghetti sauce (reserving approximately 1/2 cup). Mix well. Layer half of the mixture in a 11 x 7 inch baking dish, layer the cheese over that. Cover with remaining hamburger mixture. Spread the remaining sauce over the top. Cover with foil. Bake at 350 degrees for approximately 1 hour. Cool a few minutes before cutting.
