Spread cheese paste generously on pieces of Borodino bread, spread out slices of herring. It depends on the piece of bread, I have 3 slices. Boil the eggs the way you like. You can "hard-boil", or you can "in a bag". I like the yolk to stay viscous. Spread the egg cut in half. Again, cut off from a piece of bread as much as you want. I could fit half an egg in me. Decorate the top with green leaves. I sprinkle with parsley and finely chopped red onion. Who loves poetry, you can spread a little mustard seed on top. The toast is ready!
