First of all, we pickle the onion. To do this, cut the onion into small cubes. Add soy sauce and lemon juice to it. Meanwhile, the boiled meat is disassembled into fibers or cut into a small cube.
Cut the cucumber and tomato into a small cube.
Grate the eggs on a coarse grater. Assemble the salad in layers:
1) meat
2) egg+mayonnaise or sour cream
3) cucumber
4) pickled onion+mayonnaise
5) tomatoes
6) garnish with a sprig of parsley
