01 - Combine chicken breasts and chicken broth in a large saucepan or Dutch oven. Bring to a simmer over medium heat, cover, and cook for 18–20 minutes, or until chicken is cooked through and shreds easily.
02 - Remove chicken from the pan and shred with two forks. Pour out 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 in sauce and simmer for 10–15 minutes, stirring occasionally, until thickened and flavorful.
05 - Meanwhile, in a bowl, toss coleslaw mix with mayonnaise, apple cider vinegar, salt, and pepper until well combined.
06 - Toast sandwich buns lightly, if desired.
07 - To assemble, pile pulled chicken onto buns, top with a scoop of slaw, and add pickles if desired. Serve warm.
