sesame oil, olive oil, or other cooking oil
green onions, minced
Thinly slice steak into 1-inch wide strips.
Dip strips into a marinade made by combining garlic with rest of ingredients.
Now dip in crushed toasted sesame seeds to cover the meat completely, and return to the marinade for an hour.
Weave on bamboo sticks and broil quickly, or, if you prefer, fry quickly in a little oil.
(The sesame seeds are toasted by cooking slowly in a heavy skillet, until brown,then crushed in a mortar or heavy bowl, with salt--the mixture should not be smooth.)
