Meatball Subs
(Use leftovers of 'Pauline's Meatballs') Heat meatballs in sauce in microwave until hot! Slice 6 inch sub rolls lengthwise. Spoon meatballs with sauce into each roll. Top with shredded mozzarella cheese. Place on foil lined cookie sheet. Bake at 450 until cheese is melted, and rolls slightly toasted.
