These flank steak skewers are marinated in a delicious soy and sesame oil sauce with garlic and ginger.
Weave about 2 slices of marinated flank steak onto each bamboo skewer. Grill the skewers for approximately 2 minutes on each side for medium rare. They should be crispy and brown on the outside. Remove from the grill and serve garnished with the sesame seeds and green onions.
You can thread the meat on the skewers two hours ahead and refrigerate them until ready to grill.
