In a medium pot, add water and salt. Bring to a boil.
Add some green onions and all bean sprouts for a dip of 8-10 seconds. Bean sprouts should be crisp and not soggy.
Pour bean sprout in a colander and immediately dip in ice water for about 2 minutes. This will keep the bean sprout from being crisp.
In a bowl, add sesame oil, soy sauce, garlic, chili powder, rice wine vinegar, sesame seeds and green onions. Toss-in the bean sprouts and stir until well coated with the mixture. Refrigerate before serving.
