Rinse the champignons under cold water. This should be done quickly, since this mushroom contains 88-92% water, it does not tolerate water procedures well. Cut the champignons into small cubes.

Fry the mushrooms in a preheated frying pan with oil for 5–7 minutes.

Add finely chopped onion to the pan. Fry for another 7 minutes, stirring occasionally. When ready, leave to cool.

Peel the potatoes and grate them on a coarse grater. This will be the first layer of our salad.

Grate the cheese on a coarse grater.

Peel the eggs. Separate the yolk from the white and grate them separately on a fine grater.

Start assembling the salad. Take a small open form or salad bowl and carefully lay out the layers and grease them with mayonnaise. The sequence is as follows: 1 layer - potatoes, greased with mayonnaise; 2 layer - egg white, greased with mayonnaise; 3 layer - mushrooms fried with onions; 4 layer - cheese, greased with mayonnaise; 5 layer - egg yolk. Put the salad in the refrigerator for at least 30 minutes so that it becomes even tastier and more tender.
