Special equipment: 20 metal or wood skewers
Mix together the soy sauce, vegetable oil, sugar, sesame, ginger, green onions and garlic in a large bowl.
Cut the steak into thin strips or cubes, no more than 1/4 inch thick and 1/2 inch wide. Soak the meat in the soy sauce mixture for about 30 minutes.
String the meat on the skewers, usually 4 pieces of meat per skewer. You can also add onions and bell pepper pieces to the skewers if using.
Preheat a charcoal or gas grill. Grill the skewers until the meat is completely cooked through, 3 to 4 minutes. Serve with sticky rice, about 2 skewers per serving.
