Spoon about 1/3 of the Classico(R) Four Cheese pasta sauce into a 13x9x2-inch baking dish.
Arrange the meatballs in the Classico(R) Four Cheese pasta sauce. Pour the remaining pasta sauce over the meatballs. Sprinkle the meatballs with pepper. Top with mozzarella.
Bake, uncovered, in a 350 degree oven 30 to 40 minutes or until meatballs are heated and cheese is bubbly. If you like, serve in hoagie buns and sprinkle with additional mozzarella cheese. Makes 8 or 9 sandwiches.
