Combine the brine ingredients and submerge the chicken breasts in the brine for a minimum of 30 minutes; you can let this sit all day in the fridge until ready to cook.
Combine the dredging ingredients.
Remove the chicken from the brine, and coat in the flour mixture.
Generously spray an air fryer basket with non-stick spray, and add the coated chicken. Spray more cooking spray on top of the chicken to coat.
Air fry at 370 for 15-20 minutes (depending on the thickness of the chicken) or until an internal temperature of 165F is reached. Flip halfway through cooking.
Combine the hot sauce ingredients and coat the cooked chicken in the sauce.
Prepare the slaw.
To serve, place a coated chicken breast on a bun, top with the slaw and pickle slices.
