How to Make It
Preheat an air fryer to 380°F. Coat the basket with cooking spray.
Cut each potato lengthwise into 1/4-inch-thick slices; cut each slice into 1/4-inch fries.
Toss together the potatoes and oil in a large bowl. Season with zest, dried oregano, salt, garlic powder, onion powder, paprika, and pepper; toss to coat.
In 2 batches, cook the seasoned potatoes until crisp, about 15 minutes, flipping fries halfway through cooking time.
Return the first batch of fries to the basket, and cook until warmed through, 1 to 2 minutes. Remove from air fryer. Top fries with half of the feta, chicken, tzatziki, remaining feta, tomato, red onion, and fresh herbs.
