First, preheat your grill or smoker to medium heat.
Mix together the mayonnaise, apple cider vinegar, Worcestershire, black pepper, dark brown sugar, kosher salt, onion powder, and Everything But The Bagel Seasoning in a bowl.
Season the chicken breasts with a little extra black pepper and salt.
Cook chicken on the grill about 6 to 7 minutes per side until chicken hits 165°F inside.
When done, take chicken off the heat and let rest for a few minutes.
Use two forks to shred the chicken and toss with Alabama white sauce.
Serve the chicken on buns, optionally adding extra sauce and pickles.

Serve immediately for best taste. If storing, keep the chicken and buns separately to avoid sogginess.
