1/2 pkg. extra-wide noodles, cooked
1 sm. jar spaghetti sauce
1 c. browned, crumbed hamburger (opt.)
3 c. grated cheese, 1 c. each of your choice (e.g. Mozzarella, ricotta or cottage cheese, cheddar, Monterey Jack, Colby, brick)
1/2 c. grated Parmesan or Romano

In large microwaveable casserole, layer noodles, sauce (meat) and cheese 3 times. Sprinkle top with Parmesan. (NOTE: Use sauce sparingly or casserole will be too watery.)

Let stand about 10 minutes before serving.
