Wash the chicken fillet, put it in boiling water and cook until done. Then remove the meat from the broth, cool and cut into small pieces. Boil the eggs hard, peel them and separate the yolks from the whites. Peel, wash and finely chop the onions. Drain the liquid from the jar of mushrooms. Grate the cheese on a medium grater. Wash the dill and parsley to serve.
Prepare your ingredients. Grate the yolks on a medium grater into a container with chopped chicken fillet. Add 2 tbsp here. l. mayonnaise, salt and mix. Divide the resulting mass into two parts right inside the container. Grate the egg whites on a coarse grater and cut the canned champignons into thin slices. Mix the ingredients and divide the mass in half by analogy.
Form a salad. Place a salad bowl on a flat plate. Lay out half of the chicken-yolk mixture as the first layer, then spread a layer of mushrooms and whites (half), and then add onions. Repeat the procedure with the remaining two layer halves. When all the layers are distributed, brush the salad with mayonnaise and sprinkle generously with grated cheese.
Garnish the resulting salad with herbs for flavor and serve.
