- 1/2 cup chopped onion
- 1 (26 ounce) jar spaghetti sauce
- 14 (1 ounce) pieces string cheese

- Drain manicotti; stuff each shell with a piece of string cheese. Place over meat sauce; top with remaining sauce. Cover and bake at 350 degrees F for 24-30 min. or until heated through. Sprinkle with mozzarella cheese. Bake, uncovered, for 5-10 minutes or until the cheese is melted.
