Lay wonton wrappers on a clean, flat surface.
Place 1 teaspoon of marinara sauce in the center of each wrapper.
Top sauce with 1 tablespoon of shredded mozzarella and a pinch of chopped pepperoni.
Sprinkle with oregano and garlic powder.
Lightly moisten the edges of the wonton wrapper with water using a finger or pastry brush.
Fold the wrapper into a tight roll or envelope shape, pressing edges firmly to seal and prevent leaking.
Preheat air fryer to 375°F (190°C).
Lightly brush the exterior of each roll with olive oil.
Place rolls in the air fryer basket in a single layer, ensuring they do not touch.
Cook for 6 to 8 minutes, flipping halfway through, until golden brown and crispy.
Remove from air fryer and let cool for 2 minutes before serving.
