1 pound cooked Italian sausage
1 pound large elbow macaroni
1 pound ricotta
1 pound mozzarella cheese, thinly sliced
1 cup grated Parmasean cheese
Coarsely crumble cooked sausage. Cook macaroni according to package directions. Drain and rinse. Combine sausage, macaroni, and ricotta and mix thoroughly. Cover bottom of a 3-quart casserole with a layer of sauce, a third of the macaroni mixture, topped with sauce, slices of mozzarella, and a sprinkling of Parmasean. Repeat layers until all ingredients are used. Bake at 400 degrees farenheit for 30-35 minutes--until cheese is melted.
