01 - Preheat your oven to 350°F.
02 - In a sizable mixing bowl, combine smoked paprika, garlic powder, onion powder, salt, and freshly ground black pepper. Thoroughly coat the chicken breasts or thighs with this spice blend.
03 - Heat the olive oil in a large oven-safe skillet over medium-high heat. Sear the seasoned chicken for 2-3 minutes per side until a golden-brown crust forms.
04 - In a separate small bowl, whisk together the barbecue sauce, apple cider vinegar, brown sugar, and Worcestershire sauce. Pour this prepared sauce evenly over the seared chicken in the skillet.
05 - Cover the skillet tightly with a lid or aluminum foil and carefully transfer it to the preheated oven. Bake for 20-25 minutes, or until the chicken is thoroughly cooked and tender enough to be easily shredded with a fork.
06 - Carefully remove the skillet from the oven. Using two forks, shred the chicken directly within the skillet, then toss it with the sauce to ensure each piece is well coated.
07 - Optionally, butter the cut sides of the soft sandwich buns and toast them in a clean skillet over medium heat until lightly golden.
08 - Generously pile the BBQ pulled chicken onto the bottom half of each toasted bun. Top with a ample scoop of classic coleslaw and dill pickle slices, if desired. Complete the sandwich with the top bun and serve promptly.
