Place the chicken breasts in a slow cooker.
- In a separate bowl, combine the cherry cola, barbecue sauce, garlic powder, onion powder, smoked paprika, salt, and pepper. Stir well to combine.
- Pour the sauce mixture over the chicken breasts in the slow cooker, ensuring the chicken is fully covered. Add the sliced onions on top.
- Cover and cook on low for 6-7 hours, or until the chicken is tender and easily shreds with a fork.
- Once the chicken is done, remove it from the slow cooker and shred it using two forks.
- Return the shredded chicken to the slow cooker and mix it well with the sauce and onions. Let it cook on low for an additional 10-15 minutes to absorb the flavors.
- Toast the sandwich buns lightly in a separate pan or oven for added texture.
- To assemble, spoon the pulled chicken mixture onto the bottom half of each bun. If desired, top with a scoop of coleslaw for a crunchy contrast.
- Place the top bun on and serve immediately. Enjoy!
