Potatoes and eggs are boiled until ready, cut into small cubes. I used a steamer: cut the potatoes into cubes, and then "steamed" together with the egg-15 minutes-everything is ready. The main thing is not to forget to add salt.
The egg was cut with a vegetable cutter.. very convenient!)
Cut the green onion into rings.
Radish cut into thin rings or semi-rings, depending on the size.
