How to Make It
Set a wok over high heat until it's very hot. Add the oil. When it's very hot, add the scallions and bean sprouts and stir-fry vigorously for 1 minute, tossing and pressing the vegetables against the hot wok. Add the salt and stir-fry for 1 minute. Add the soy sauce and rice vinegar and stir-fry for 30 seconds to 1 minute longer. Transfer to a plate and drizzle with the sesame oil. Toss gently and serve immediately.
