Prepare sauce by mixing together all sauce ingredients in a small bowl or shake them all up in a mason jar. Remove 1/3 cup for later. Place the remaining sauce in a large baggie with chicken. Toss and seal. Place in fridge and let marinate for at least 30 minutes.
Preheat grill to high heat. Lay a piece of tin foil down and spray with nonstick cooking spray. Cook skewers on grill for about 5 minutes and then flip for another 5 minutes and until chicken is cooked through.
Makes 10-12 skewers.
