In a small microwave-safe bowl, combine the soy sauce, oil, honey, ginger root and garlic. Heat in microwave on medium for 1 minute, then stir. Heat again for 30 seconds, watching closely to prevent boiling.
Place chicken breasts in a shallow dish. Pour soy sauce mixture over, and set aside to marinate for 15 minutes.
Preheat barbecue for medium-high heat. Drain marinade from chicken into a small saucepan.
Bring to a boil, reduce heat and simmer over medium heat for 4-5 minutes. Set aside for basting.
Lightly oil the barbecue hot plate.Cook chicken for 6 to 8 minutes each side, or until juices run clear when skewered.
Baste frequently with remaining marinade. Chicken will turn a beautiful golden brown.
