Slice the boiled squid.
I have a regular cucumber, so I cut it lengthwise into two parts and removed the middle with the seeds.
Cut the cucumber diagonally into not very thin slices, and the onion into thin half-rings.
For the sauce, mix chili, soy sauce, sesame oil, powdered sugar, vinegar, salt and pepper.
Mix the sauce with the squid, then add the onion and cucumber and mix, maybe add vinegar or sugar to taste – I just had enough.
Put it in a salad bowl, sprinkle with finely chopped green onions and serve to the table!
