Broil 4 to 5 inches from the heat (I used the middle rack) for 15 to 20 minutes or until chicken is light brown, turning once halfway through broiling.
In a medium bowl, combine barbecue sauce, honey, mustard and Worcestershire sauce.
Layer a small amount of sauce in the bottom of the slow cooker. Place the chicken on top and pour the sauce over the chicken.
Cover and cook on low for 3 to 4 hours or on high for 1 and ½ to 2 hours.
Notes
I reserved some of the sauce and basted 30 minutes before serving. I sprayed my baking sheet and slow cooker with nonstick cooking spray.
