Make a cut through the chicken parallel and beside the backbone.
This will enable you to butterfly the chicken.
Once the chicken is opened, pop the keel bone or breast bone (the dark bone separating the two breasts) out of the chicken.
Lightly coat each side of chicken with olive oil.
Sprinkle salt on both sides and place skin side up on the grill away from the hot coals.
Cook using indirect heat for 1 hour 30 minutes at 300 degrees.
Flip chicken and season "meat side" with coarse ground black pepper.
Cook for an additional 1 hour 30 minutes at 300 degrees.
Remove the chicken from the grill and submerge in a pan of Alabama white sauce.
Cut and serve.
