Shallots (I have a big picture, but I changed my mind at the last moment and took a small shallot onion) cut lengthwise into strips, finely chop green onions.
Mix it all in a bowl with fish, pour the prepared sauce and mix. Taste.
Here you can diversify the sharpness of the salad by adding ground chili pepper and salt to taste, if you are not satisfied with it. Put it to marinate in the refrigerator for 2-3 hours.
