1. Combine all marinade ingredients in a food processor and process until smooth and somewhat thickened. Set aside a third of the mixture to use as a dipping sauce.
2. Place the remaining marinade, along with the chicken breasts, in a large mixing bowl. Allow to marinate in the refrigerator for at least 30 minutes, or up to four hours.
3. Preheat oven to broil.
4. Slice each chicken breast in half lengthwise. Thread chicken onto skewer, pushing the chicken in and out to achieve a ruffled effect.
5. Place chicken skewers onto broiler pans and broil on lower rack for eight minutes on each side. Remove from oven and cover with foil until ready to serve.
