Liberally sprinkle the chicken breasts with salt and pepper and place in the bottom of the slow cooker.
On a small bowl, mix together all of the other ingredients. Pour the mixture over the chicken breasts, making sure that the breasts on the bottom are coated with the mixture.
Set the slow cooker to LOW and cook for 6-8 hours, until the chicken reaches 165 degrees on a meat thermometer.
Remove the chicken to a large plate, and turn the slow cooker to HIGH.
Using tongs and/or forks, shred the chicken into small pieces.Set aside.
With the slow cooker set to high, stir the sauce mixture to release steam and allow the sauce to thicken, about 5 minutes. Turn the slow cooker off.
Place the shredded chicken back into the slow cooker with the thickened sauce and stir until fully mixed and all of the chicken is coated with sauce.
Pile the shredded chicken onto sandwich buns, then top with Ranch Coleslaw. Serve and enjoy!
