Step 1

Cut onions, peppers, and chicken into thin slices. Dry chicken extra with paper towels if needed.

Step 2

Add chicken to a bowl and sprinkles with fajita seasoning, cornstarch, and drizzle with 2 tsp oil. Stir together extra well so that chicken is coated nicely. I like to use my hands (with food safe gloves on) just to make sure it's completely coated, but a spoon works.

Step 3

Add peppers and onions to bowl and drizzle with 1 tsp oil and a pinch of salt and pepper. Stir all together.

Step 4

Preheat Air Fryer to 400 degrees. When preheated spray basket with cooking spray then add chicken mixture. Cook for 10-12 minutes, but during the cook time stop and shake basket to ensure cooking and char on the chicken evenly.
