Wash, cut, and drain string beans in a paper-towel lined bowl.
Stir in oil, not quite 1/4 cup, coating the bottom of the pan. On HIGH heat, add cut and drained string beans after the oil is sufficiently hot (it'll sizzle when you put a bean in if it is hot enough).
Stir about till you see nice wrinkles on all the beans (7-8 min for this recipe size). Remove beans from skillet and let drain on a paper towel in a bowl. Dump all but 1 tablespoon oil out.
Add scallions and garlic, and stir till fragrant on medium-high heat(30 sec).
Add the sauce, dried chili peppers, and stir for 10-20 seconds until fragrant.
Add cooked beans, and stir on medium - low heat till beans are well coated.
Serve hot, with a bowl of rice!
Notes
Drain the beans by placing them in a bowl lined with a paper towel, prior to cooking in oil. If the beans have water on them, that will cause popping in the oil which can be messy.
