In a 9 x 13-inch greased baking dish, layer with 1/4-inch slices of eggplant. Sprinkle with Parmesan cheese, bread crumbs and mozzarella cheese; pour spaghetti sauce over all. Repeat layers until pan is full, ending with the Parmesan and mozzarella cheeses. Cover and bake at 350 degrees for 1 hour or until eggplant slices are done.
