Peel the onion, cut into half rings and marinate in a mixture of water, vinegar, soy sauce and sugar.
Boiled sausage cut into thin cubes.
Eggs slightly shake a fork, add starch and vegetable oil. Carefully beat with a fork to avoid lumps and fry thin pancakes.
Cut them into strips and add to the sausage. Drain the marinade from the onions, to try if you want, you can rinse it slightly and put in a salad bowl. Season with mayonnaise (a little), mix and you can try.
