Begin by rolling out your pizza dough on a lightly floured surface to about ¼ inch thickness.

In a bowl, combine the mozzarella cheese, ricotta cheese, diced bell peppers, pepperoni, Italian seasoning, salt, and pepper, mixing well.

Cut the dough into circular pieces, about 6 inches in diameter and place the cheese mixture on one half of each circle.

Fold over the dough to create a half-moon shape and pinch the edges tightly or crimp with a fork.

Preheat your air fryer to 375°F (190°C).

Brush the top of each calzone with olive oil and place them in the air fryer basket, ensuring they are not touching.

Cook for about 8-10 minutes or until they are golden brown and crispy.

Let the calzones cool slightly before serving, ideally with a side of marinara sauce for dipping.
