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 chicken is cooked through and shreds easily.
02 - Remove chicken from the pan and shred using two forks. Drain any 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 and heat over medium-low until bubbling.
04 - Add shredded chicken back to the pan. Toss to coat evenly in sauce and simmer for 10–15 minutes, stirring occasionally, until sauce thickens and flavors meld.
05 - In a mixing bowl, combine coleslaw mix, mayonnaise, apple cider vinegar, salt, and pepper. Toss until vegetables are evenly coated.
06 - Lightly toast sandwich buns for added texture and to prevent sogginess.
07 - Pile pulled chicken onto toasted buns, top with a generous scoop of coleslaw, and add pickle slices if desired. Serve immediately while warm.
