Preheat grill to medium-high heat. Combine sugar and spices in a resealable plastic bag. Wash hands. Add chicken to bag, one piece at a time, shaking to coat. Transfer to plate. Spray on both sides with nonstick cooking spray. Wash hands.
Grill chicken, turning frequently to avoid burning sugar, 10 to 12 minutes or until done (internal temperature 170° F).
Serving Suggestion: Serve chicken with corn bread, coleslaw and barbecue sauce for dipping. Refrigerate leftovers.
Tip: To substitute Individually Frozen Boneless, Skinless Chicken Breasts, rinse off ice glaze and pat dry before placing in bag with spices and increase cooking time by about one-third.
