Crusty rolls are filled with ready-made meatballs, simmered in Italian sauce and topped with mozzarella cheese to make these hearty supper sandwiches.
Step 1
Heat the sauce and meatballs in a 3-quart saucepan over medium-high heat to a boil. Reduce the heat to low. Cook for 20 minutes or until the meatballs are heated through, stirring occasionally.
Step 2
Spoon the meatballs and sauce into the rolls. Top with the mozzarella and Parmesan cheeses.
