Baked mmmm...Mostaccioli

1 lb. box of Barilla Mostaccioli
1 1/2 pounds lean ground beef
1 small onion, chopped
2 (24 ounce) jars of your favorite spaghetti sauce
1 1/2 cups of shredded part-skim mozzarella cheese
1/4 cup grated Parmesan cheese

Cook mostaccioli according to package directions. Meanwhile, in a large saucepan cook ground beef and onion over medium heat until meat is crumbly and no longer pink; drain. Stir in the spaghetti sauce.

Drain the mostaccioli. Spread 1/2 cup of the meat sauce into an 11 inch x 7 inch baking dish coated with cooking spray. Layer with half of the mostaccioli, meat sauce and mozzarella cheese. Add a second layer of the remaining mostaccioli, meat sauce and mozzarella cheese. Sprinkle with Parmesan cheese (dish will be full).

Bake, uncovered, at 350 degrees for 30-40 minutes or until bubbly and heated through. Makes 6-8 servings.
