Prepare dough by letting store-bought pizza dough reach room temperature for about 30 minutes. Roll it out if using homemade dough.

In a large mixing bowl, combine ricotta, mozzarella, Parmesan, cooked meats, fresh spinach, oregano, garlic powder, salt, and pepper. Mix until well combined.

Roll out the prepared dough again to ensure even thickness, about 1/4 inch thick.

Cut the rolled-out dough into circles, each 6-8 inches in diameter.

Fill half of each dough circle with a generous spoonful of the filling, leaving a 1/2 inch border.

Fold the dough over the filling, pinching the edges to seal securely.

Preheat the air fryer to 375°F (190°C) and brush the tops of each calzone with the egg wash.

Air fry calzones for 10-15 minutes until golden-brown and crispy.

Let the calzones cool for a few minutes on a wire rack before serving.
