DO-AHEAD TIP: Marinate chicken for 30 minutes (15 minutes in refrigerator and 15 minutes at room temperature - see recipe).
Preheat grill to MEDIUM.
Place chicken in a large zipper-topped plastic bag. In a small bowl, combine remaining ingredients; pour mixture over chicken, seal bag and gently massage marinade into chicken.
Refrigerate for 15 minutes then bring to room temperature. Lightly oil the grill grate and cook chicken over indirect heat for 6 to 8 minutes per side or until juices run clear.
Watch carefully to prevent burning!
