Preheat your grill or set up the coals for medium heat.
Pull the skin off the chicken. Season with smoked salt and pepper.
Place chicken on the grill. Cook for 7 minutes on each side. Then start adding the barbecue sauce. Brush on the first side and then cook for 2 minutes. Flip and brush barbecue sauce on the second side. Cook for another 2 minutes. Flip back to the first side, brush on more barbecue sauce, and cook for a final 2 minutes.
Serve with extra barbecue sauce on the side (just not the sauce you used to brush on the cooking chicken).
