Removed the skin from the chicken. Pull off the meat. Now pull that meat into shreds and set in a bowl. (The chicken can be prepared to this point several hours in advance. Cover and refrigerate until ready to reheat.)
Place the barbecue sauce, apple juice, vinegar, hot pepper sauce and Worcestershire in a wide skillet. Bring to a simmer, and then stir in the chicken. Cook 5 to 7 minutes, or until the chicken is hot. Set a lettuce leaf on each bottom bun. Divide and mound chicken on each bottom bun. Top the chicken on each bun with a slice of onion and pickle. Set on top buns and enjoy.
