Chop 2 green onions. Place in plastic bag with teriyaki sauce, ginger and garlic. Add beef and chicken; seal. Refrigerate 30 minutes to 2 hours.
Cut remaining onions in 2-inch pieces. Thread beef and half of green onions alternately on four 10-inch skewers. Repeat with chicken and remaining onions on 4 more skewers.
Preheat broiler. Broil skewers 6 inches from heat for 6 to 8 minutes or until chicken juices run clear when pierced with a knife. Makes 4 servings.
