Preheat your air fryer to 375°F (190°C).
Place your flatbread on a clean surface or on a piece of parchment paper.
Spread a thin layer of marinara sauce over the flatbread, leaving a small border around the edges.
Sprinkle shredded mozzarella cheese evenly over the marinara sauce.
Arrange thinly sliced fresh tomatoes on top of the cheese.
Drizzle a little olive oil over the assembled pizza.
Carefully transfer the pizza to the air fryer basket or tray.
Cook the pizza in the air fryer for 6-8 minutes, or until the cheese is melted and bubbly, and the edges of the flatbread are golden brown.
Once cooked, remove the pizza from the air fryer and let it cool for a minute before slicing.
Tear fresh basil leaves and scatter them over the pizza.
