6 boneless chicken breasts
1 (8 oz.) pkg. Mozzarella cheese
1 (16 oz.) jar meatless spaghetti sauce

Place chicken in a greased, shallow baking dish and pour sauce over it. Cover. Bake at 350 degrees for 45 minutes (spooning sauce over now and then). Put cheese (sliced or grated) over chicken. Bake until cheese melts, uncovered.
