Slice your bell peppers and onions. I like to go for larger chunks, but you can do whatever size you prefer, larger is just less likely to catch and burn in the air fryer.
Add your chicken breasts to a bowl.
Spread the fajita seasoning over the top of the chicken and then rub it across the breasts well.
Lightly oil your air fryer basket if you'd like. You can use spray oil or just a little drizzle of olive oil.
Add the chicken mini fillets to the basket.
Air fry at 200C (400F) for 10 minutes.
Add the peppers and onions here. Air fry at 200C (400F) for another 6-8 minutes
If your air fryer basket is quite crowded then be sure to give the basket a shake every 5 minutes during the cooking time to ensure even cooking.
Check the temperature before serving. The safe internal cooking temperature of chicken is 74C (165F). Make sure there is no pink meat remaining for safe serving.
When serving you'll want to decorate with your favourite dressings; salsa, sour cream and guacamole all work very well! I love to make homemade wraps but the shop bought ones work very well and are cheap enough!
Squeeze on a little lime, or lemon, juice for a bit of added flavour.
