Preheat grill to medium heat. (If using the Foodi Grill, make sure the grill plate is installed prior to preheating).
Season chicken well with the tenderizer
In batches if needed, add chicken in a single layer on the hot grill.
Grill for 7 minutes over medium heat.
Flip chicken to uncooked side and grill for 7 more minutes or until cooked through, tender and juicy. (If using a meat thermometer check to make sure largest pieces are cooked beyond 170 for best results.)
