Flatten your chicken by removing the backbone with sharp kitchen shears or using a knife. Drizzle the chicken with olive oil and season on all sides with salt and pepper.
Add the chicken to a hot grill (450° to 550°), skin side down and cook for 6 to 8 minutes making sure it does not burn and does not stick to the grill grates.
Turn the heat down to 350° to 400°, close the grill door and cook for 20 to 25 minutes. Flip the chicken over and place on a cooler side of the grill and then turn the heat back up to 425° to 450°.
