Cut the tuna into cubes and fry for a few minutes in olive oil until golden brown. Tuna cooks very quickly.
Chop the Chinese cabbage, slice the cucumber and onion.
Cut the eggs into thin strips.
The salad is prepared in layers. Place some of the chopped Chinese cabbage in a salad bowl, then the cucumber.
Place the eggs as the third layer and generously coat them with mayonnaise.
Next, place the tuna, onion and the second half of the Chinese cabbage in a salad bowl.
Grease the Chinese cabbage generously with mayonnaise. Let the salad soak and serve. Enjoy!
