Preheat the air fryer to 350°F (175°C).

Slice each pita bread into 8 equal triangles using a knife or kitchen shears.

In a large mixing bowl, whisk together the olive oil, salt, garlic powder, and dried oregano.

Add the pita triangles to the bowl and toss until evenly coated with the oil mixture.

Arrange the pita triangles in a single layer in the air fryer basket, working in batches if necessary to avoid overcrowding.

Air fry for 5 to 7 minutes, shaking the basket halfway through the cooking time, until the chips are golden brown and crisp.

Remove from the air fryer and allow to cool on a wire rack for 5 minutes to reach maximum crispness.
