grilled BBQ chicken

I had grilled chicken for lunch yesterday, it was delicious and only 3 ww points! Can't beat that! What's your favorite grilled chicken recipes ?

Here's one of mine...

2 Tbsp. brown sugar
1 tsp. dry mustard
1 cup ketchup
1/4 cup water
2 Tbsp. apple cider vinegar
1/2 tsp. onion powder
1/8 pepper
2 lbs. boneless, skinless chicken breasts

Directions

Combine all ingredients except chicken in a small saucepan and cook over medium heat until boiling. Reduce heat and simmer for 5 minutes. Cool for 30 minutes. Brush on chicken breasts; cover meat and remaining marinade and refrigerate for 1-2 hours.
Bring remaining marinade to a boil again and cook for 2-3 minutes. Meanwhile, remove chicken from marinade and cook on George Foreman two sided grill for 4-6 minutes until thoroughly cooked. Serve with hot marinade.
