In a small bowl combine all ingredients except chicken, and beat with wire whisk until blended. Place chicken in shallow dish and pour mixture over chicken and let marinate, covered, at room temperature for 15 minutes. Chicken may be grilled over medium heat or broiled. Grill for 8-10 minutes on each side or broil 4-6 inches from heat for 8-10 minutes turning once. Chicken does not absorb much of the oil in the marinate mixture.
