Wash the mini peppers and pat them dry. Slice each pepper lengthwise and remove the seeds and membranes.

In a medium mixing bowl, combine the feta cheese, cream cheese, olive oil, garlic powder, dried oregano, and black pepper. Mix until well blended.

Stuff each pepper half with the feta mixture, using a spoon to fill them evenly.

Preheat your air fryer to 375°F (190°C) for 3 minutes.

Place the stuffed peppers in a single layer in the air fryer basket. Avoid overcrowding to ensure even cooking.

Air fry the peppers for 8-10 minutes, or until the peppers are tender and the cheese is lightly golden and bubbly.

Carefully remove the peppers from the air fryer and let them cool for a minute. Garnish with chopped fresh parsley if desired before serving.
