01 - Place chicken breasts and broth in a large saucepan or Dutch oven. Bring to a simmer over medium heat, cover, and cook for 18–20 minutes until fully cooked and easily shredable.
02 - Transfer cooked chicken to a cutting board and shred using two forks. Drain and discard excess liquid from the pan.
03 - In the same pan, combine barbecue sauce, brown sugar, apple cider vinegar, smoked paprika, garlic powder, onion powder, and black pepper. Stir constantly over medium-low heat until mixture bubbles.
04 - Add shredded chicken to the sauce mixture. Toss thoroughly to coat and simmer for 10–15 minutes, stirring occasionally, until sauce thickens and flavors meld.
05 - In a medium bowl, combine coleslaw mix, mayonnaise, apple cider vinegar, salt, and pepper. Toss until evenly distributed.
06 - Lightly toast sandwich buns in a skillet or toaster for enhanced texture and flavor.
07 - Mound saucy pulled chicken onto the bottom buns, top with a generous scoop of coleslaw, add pickle slices if using, and crown with the top bun. Serve immediately while warm.
