For the sauce, finely cut the wild chives, put into bowl, add 2 tbsp of soy sauce, pinch of sugar, 1 tablespoon of sesame oil. The mixture should not be too watery. You can substitute wild chives with green onion. If it is watery, add more chives or green onions. If you want it to be a little spicy, add some ground red pepper (the ones used to make kimchi).
