Cut off the ends of the green beans, unless they are very fresh and thin. Lightly steam the beans while frying the garlic and ginger in the oils over low heat. You want the garlic to turn a golden color and become very aromatic—at this point you can add the red pepper flakes, green beans, soy sauce and the water. Cover and cook everything together over high heat for a few minutes until the water evaporates and the beans look shiny from the oil. Shake the pan and stir occasionally while cooking. Garnish with sesame seeds and enjoy! Yields 4 cups.
