Place the chicken in a large plastic food storage bag. Pour the dressing over it and seal the bag tightly. Shake everything together using your hands to make sure the chicken is fully coated. Place on a plate or bowl and chill in the fridge overnight.

Heat a stove top or outdoor grill over medium-high heat. Grease with a bit of oil or cooking spray. Carefully place the chicken, draining most of the dressing off each piece, on the hot grill. Cook for about 3 to 4 minutes on the first side. Flip over and cook for 2 to 3 minutes on the second side. Brush the chicken with BBQ sauce and flip over. Continue to brush each side with BBQ sauce, flipping and cooking for about 10 minutes. You'll know the chicken is done when the internal temperature reads 165 degrees, with a cooking thermometer.

Transfer to a plate or platter and cover loosely with foil. Allow to site about 10 to 15 minutes before slicing and serving.
