Boil water in a pot, add a pinch of salt, and cook the green onions starting from the roots until tender. Add the green parts of the green onions and bean sprouts, blanch briefly, and drain.

Remove the roots of the green onions, cut them in half, and scrape off the slimy texture using the back of a knife. Cut into 3–4 cm pieces.

In a bowl, mix the green onions, bean sprouts, and sesame oil.

In a separate bowl, combine all the seasoning ingredients (sugar, salt, vinegar, soy sauce, and garlic).

Add the seasoning mixture to the vegetable bowl and toss to combine.
