Separate the bagels, and place them and top each bagel half with sauce, cheese and desired toppings.
Place in the basket of the air fryer and cook for 5 minutes or until the cheese is melted.
You'll know the pizza bagel bites are done when the cheese is completely melted slightly browned. If you prefer extra crispy bagel pizzas, you can let them cook a little longer until the cheese browns on top and the bottom gets extra crunchy. Note, the cheese will not bubble like it does in the oven.
