Prepare the ingredients: chop the vegetables, shred the cheese and measure the milk. Heat a small ovenproof skillet over medium to high heat

Once the skillet is hot, add the vegetables and cook them until they begin to turn soft. Turn the heat off.
Sprinkle the cheese over the top of the vegetables in the skillet, then pour the eggs over.
Place the pan into a preheated 375 degree air fryer and cook for 8 to 10 minutes until the top turns golden brown and the center of the frittata is firm.
