Air Fryer Pepperoni and Peppers Stromboli cook up perfectly in just 13 minutes. Wonderfully crunchy on the outside with lots of cheese, pepperoni, and peppers on the inside. Perfect for game day, having guests over, or a family meal. I am completely in love with my Air Fryer. It cooks foods so fast and gets them fabulously golden and crispy on the outside. You won’t believe how delicious this Air Fryer Stromboli tastes! And there are endless variations you can make. What a great way to use up all the leftovers in your fridge and have an economical meal. For this one, I used mozzarella cheese, pepperoni, peppers, and a few onions.
