First, prepare chicken breasts by thinly slicing into 1-inch thick strips. Stick a wooden skewer through each piece of chicken breast and place onto a large plate.
Season both sides of the chicken breast with a generous amount of dry rub. You should use between 3-4 tablespoons per 1 lb. of chicken.
Next, preheat grill to 400ºF. Once the grill is hot, carefully spray the grates with nonstick cooking spray or rub with olive oil.
Grill skewers at 400ºF for 7-10 minutes, flipping half-way through.*
Once the chicken is almost cooked, use a brush to paint BBQ sauce onto both sides and grill for 1 more minute to caramelize.
Notes
*How long the chicken grills depends on how thick the chicken is cut.
