This German dish looks like a vinaigrette. But he has a completely different taste, which can be changed at will by choosing herring of different salting.
Wash potatoes and beets thoroughly with a brush, boil in their skins. Drain water and let vegetables cool. Peel the vegetables from the skin and cut into small cubes.
Cut the apple into 4 parts, remove the core, cut into the same cubes, sprinkle with lemon juice. Peel the onion, cut into thin rings. Wash green onions, cut diagonally into thin rings.
Put potatoes, beetroot, apple and onion in a bowl, add green peas, sunflower oil and mix. Transfer to a serving platter. Arrange herring pieces nicely on top. Sprinkle salad with green onions.
