Preheat your air fryer to 375 degrees F (190°C) for 3-5 minutes.
Place your flatbread or pre-made pizza crust on a clean surface, drizzle with olive oil, and sprinkle garlic salt.
Use the cheese to make a well for 1-2 eggs in the center of the pizza. This will help keep the egg whites from running off the side of the bread.
Halve the cherry tomatoes and dice or rip the prosciutto into small pieces. Place the cherry tomatoes and prosciutto on top of the pizza, leaving the middle of each well open for the egg.
Carefully place an egg into the middle of each well. To keep the eggs intact, crack each egg separately into a small bowl and then tip the egg from the bowl onto the top of the pizza.
Carefully transfer the prepared pizza to the preheated air fryer basket or tray. Cook for about 5-7 minutes, or until the cheese is melted bubbly and the edges of the flatbread are crispy.
Once the breakfast flatbread pizza is cooked to your liking, carefully remove it from the air fryer. Let it cool for a moment before slicing and serving.
