Prep the Chicken: Cut the chicken into bite-sized chunks. The easiest way to do this, is cut the chicken breast in half vertically, and then cut those strips into bite-sized pieces.
Air Fry the Chicken: Spray your air fryer basket with non-stick cooking spray, and arrange the chicken bites. Depending on the size of your air fryer basket, you may need to do this in a couple of batches.
