Grilled Chicken with Citrus-BBQ Glaze

Whisk barbecue sauce, orange zest, orange juice, oil, garlic powder, paprika, salt and pepper in a large bowl. Remove 1/2 cup sauce for basting. Add chicken pieces to the remaining sauce in the bowl and toss to coat well. Refrigerate for at least 15 minutes.

Preheat grill to medium heat (325°F). Grill chicken for 5 minutes per side, basting with the reserved sauce once. Reduce heat to medium-low and continue grilling and basting often until an instant-read thermometer inserted into the thickest parts registers 165°F, 15 to 20 minutes more. (Discard any remaining marinade.)

Serve sprinkled with parsley and garnished with orange slices, if desired.
