Place the turkey breast into the slow cooker. In a small bowl add the Frank's red hot, honey, pepper and melted butter, stir until smooth. Pour HALF of this sauce over the turkey breast in the slow cooker. Save the remaining sauce in the fridge.
Cover and cook on LOW for 5 hours.
Heat the remaining sauce in the slow cooker in the microwave until warmed. Remove the turkey breast from the slow cooker and remove skin and bone. Slice and serve with the warmed sauce.
