How to make
Boil the eggs and cut them into quarters. Cut the onion into thin wheels, mash it lightly with salt and arrange on a plate next to the chopped eggs.
Distribute the chopped crab rolls, mushrooms, and corn next to each other, and put 2 tablespoons of potato salad (boiled potatoes + mayonnaise) in the middle.
Season the salad with spices to taste, add a little lemon juice, vinegar and olive oil and serve with chopped parsley.
