Slice your bread in half lengthwise, and then cut those in thirds.
Place two pieces of bread in the basket of your air fryer. Set the air fryer to 400°F for 3 minutes. Once cooked, switch the bread with the two uncooked pieces and cook those for 2 minutes.
Spread the sauce over the bread.
Sprinkle the cheese, garlic, and Italian seasoning over the sauce.
Place the pepperoni over the cheese.
Place two of the pizzas into the air fryer at 400°F for 5 minutes. Swap out the pizzas for the uncooked ones and cook those for 4 minutes or until golden brown.
