Preheat the Air Fryer to 200°C or 390°F for approximately 3 minutes depending on your air fryer.
Slice the long bread rolls down the middle being careful not to slice all the way through.
Place the precooked meatballs in the Air Fryer basket and cook for approximately 9 minutes.
Place the cooked meatballs in the long bread roll, add 2 tbsp pizza sauce, and sprinkle grated Mozzarella Cheese on top.
Place the rolls back in the air fryer and cook for 2-3 minutes until cooked.
Tip: Use Mozzarella cheese as it melts better, and is less oily. Note: Pack the mozzarella cheese well in the roll otherwise it will fly out during cooking. If you have a small rack you can place on top of the rolls, it will help stop cheese from flying all over the air fryer.
