3 tablespoons vegetable or peanut oil for stir-frying, or as needed
Wash the green beans and drain thoroughly. Trim the ends and cut
on the diagonal into pieces approximately 2 inches long.
Combine the sauce ingredients and set aside.
Heat the wok on medium heat and add 2 tablespoons oil, drizzling
the oil down the sides of the wok. When the oil is hot, add the
beans. Stir-fry for 7 - 10 minutes, until their skins pucker and
turn brown and the green beans are tender without being mushy. Remove
the beans from the wok.
Heat 1 tablespoon oil in the wok on medium-high heat. When the oil
is hot, add the chopped garlic, ginger and scallions. Stir-fry briefly
for a few seconds until aromatic. Add the chili paste.
Add the sauce and the green beans. Toss the ingredients together
and serve hot.
