1. Prep the Chicken: Start by tossing the bite-sized chicken pieces with salt, pepper, and cornstarch until they are well-coated. This step ensures that your chicken will have a delicious, crispy exterior after air frying.

2. Air Fry the Chicken: Preheat your air fryer to 375°F. Once heated, arrange the chicken bites in a single layer in the air fryer basket. Make sure they are not touching to allow for even cooking. Cook for 10 minutes, then shake the basket or turn the pieces over, and cook for an additional 10 minutes until the chicken is golden brown and cooked through.

3. Make the Honey Garlic Sauce: While the chicken is cooking, prepare the sauce. In a small saucepan, combine honey, soy sauce, minced garlic, apple cider vinegar, sesame oil, and crushed red pepper flakes if using. Bring the mixture to a simmer over medium heat, stirring occasionally. Let it simmer for about 5 minutes, or until the sauce thickens slightly.

4. Combine and Serve: Once the chicken is done, toss it in the sauce until each piece is well-coated. If you like, sprinkle with sesame seeds and chopped green onions for garnish.
