Crock Pot BBQ Chicken

4-6 pieces boneless skinless chicken breasts (you can throw them in frozen... even easier!)
1 bottle BBQ sauce (your favorite--mine is KC Masterpiece)
1/4 c vinegar
1 tsp. red pepper flakes
1/4 c brown sugar
1/2 - 1 tsp. garlic powder

Mix BBQ sauce with all ingredients listed under it. place chicken in crockpot. pour sauce over it and cook on LOW for 4-6 hours. you pretty much don't even have to stir it...SO EASY!
