Start by cleaning off the chicken, removing all of the visible fat. Rinse the chicken and then cut it into 6-inch pieces.
Spread the honey mustard generously over the chicken.
Mix the breadcrumbs, parsley, melted butter, garlic powder, salt, and pepper in a small bowl.
Then dip the coated (with the honey mustard) chicken into the breadcrumb mixture. As you coat them, place them in your air fryer basket.
After you finish breading all of the chicken, spray REALLY GENEROUSLY the chicken with cooking spray.
Set the temperature to 370 degrees F, air fryer setting, for 10 to 12 minutes.
Check your chicken with a meat thermometer. When the temperature reads 165 degrees F, remove the chicken.
Plate, serve, and enjoy!
