Preheat the air fryer: Set it to 375°F (190°C) for 3–5 minutes.
A hot basket gives the flatbreads a crisp bottom.
Prep the chicken: If your chicken isn’t seasoned, toss it with a pinch of salt, pepper, and a spoonful of pesto. This infuses flavor and keeps it moist.
Warm the flatbreads (optional): Lightly brush with olive oil and air fry for 1–2 minutes per side to pre-crisp. This helps prevent sogginess once the toppings go on.
Assemble: Spread each flatbread with 1–2 tablespoons of pesto.
Sprinkle on mozzarella, then add chicken, tomatoes, and red onion. Finish with a little more cheese if you like.
Air fry: Place the loaded flatbreads in a single layer. Cook at 375°F (190°C) for 5–7 minutes until cheese is melted and edges are golden.
Work in batches if needed.
Add greens and finish: Top with a handful of spinach or arugula right after cooking so it softens slightly. Add a squeeze of lemon, a shower of Parmesan, and red pepper flakes.
Season to taste: A pinch of salt and black pepper at the end makes the flavors pop. Slice and serve hot.
