Whisk together all the ingredients (but chicken) in a mixing bowl. Set aside about ½ of this marinade for during and after grilling.
Place chicken in a large, resealable plastic bag. Pour in the marinade portion and seal bag. Refrigerate for 2-4 hours.
Preheat an outdoor grill for medium-high heat. Thread chicken chunks onto skewers, piercing once near the middle. Discard the marinade from the bag.
Prepare grill (oiling grate, etc.). Cook chicken for about 5 minutes per side until chicken is cooked through and both sides are golden brown, baste frequently with reserved marinade.
After grilling, pour any remaining marinade over chicken and serve.
