Combine the BBQ sauce, Worcestershire sauce, brown sugar and red pepper flakes in a small bowl.
Lay the chicken breasts in the bottom of the slow cooker. Pour the sauce over the chicken and turn to coat. Place 2 paper towels under the lid of the slow cooker to prevent excess moisture.
Cook on HIGH for 3-4 hours or LOW 5-6 hours or until chicken breasts reach 165° minimum and shred easily.
Pull the chicken breasts apart with two forks, add a bit more sauce if necessary, and serve on slider buns topped with coleslaw.
Notes
Leftovers can be kept in the fridge for up to three days and re-heated.
