Serve these chicken bites as an appetizer with dipping sauces like ranch dressing or BBQ sauce, or enjoy them in a wrap or sandwich. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the air fryer or oven to maintain crispiness. For extra flavor, marinate the chicken pieces in buttermilk for a couple of hours before cooking. Do not overcrowd the air fryer basket.
