Juicy homemade meatballs simmered in a rich tomato sauce, topped with melted mozzarella and provolone cheese, served in soft sub rolls. Perfect for feeding a crowd with minimal effort and maximum flavor.
For juicier meatballs, mix beef and pork. Let meatball mixture rest in fridge for 30 minutes before shaping. Turn meatballs halfway through baking for even browning. Simmer sauce gently to avoid acidity. Toast rolls lightly before filling to prevent sogginess. Watch broiler carefully to avoid burning cheese.
