In a large saucepan, combine shredded chicken and BBQ sauce. Cook over medium low heat, stirring often, until the chicken is well coated in sauce and is warmed through, about 5 minutes. Remove from heat.
To assemble, add about a heaping ½ cup of chicken to the bottom of each roll. Top with a heaping pile of slaw, and add pickles on top, if desired. Add top roll and serve warm.
Notes
The nutrition label includes the brioche buns.Storage: Store the separate components in airtight containers in the refrigerator. The BBQ shredded chicken can be kept in the fridge for up to 4 days, while the coleslaw will last up to 2 days before it starts losing its crunchy texture. If the sandwiches are already assembled, I recommend separating the chicken and coleslaw from the buns in order to store them properly.
