01 - Place chicken breasts in the bottom of the slow cooker in a single, even layer.
02 - In a mixing bowl, whisk together the barbecue sauce, honey, Worcestershire sauce, garlic powder, onion powder, smoked paprika, and black pepper until smooth and well combined.
03 - Pour the sauce mixture evenly over the chicken breasts, ensuring all pieces are coated.
04 - Cover and cook on low heat for 4 to 5 hours, or on high heat for 2 to 3 hours, until the chicken is tender and reaches an internal temperature of 165°F.
05 - Transfer the cooked chicken to a cutting board and shred using two forks. Return the shredded chicken to the slow cooker and stir thoroughly to coat with the sauce.
06 - Serve hot, garnished with fresh chopped parsley if desired. Pairs well with rice, in sandwiches, or alongside roasted vegetables.
