Small sandwiches with herring and egg

Ingredients

→ 30 G MUSTARD, TOMATO OIL OR BUTTER WITH THE HORSERADISH
→ 1-2 HARD-BOILED EGGS
→ 100 G (4 SLICES) BLACK BREAD
→ 1 TABLESPOON CHOPPED GREEN ONION
→ 1 TABLESPOON THICK SOUR CREAM (20% FAT CONTENT)
→ 1 TOMATO OR 1 SMALL FRESH CUCUMBER

Spread the bread with butter (see fig ."Tomato butter for sandwiches", "Butter with horseradish"), peel the herring, remove the bones (see "Cutting fish"), and then cut into thin strips.

Chop the egg yolk and white separately. Chop the tomato or cucumber and green onion with a knife. Put the products in long multi-colored strips, and it is recommended to put a strip of sour cream next to the herring.

Cut the sandwich completely covered with ingredients into four-and triangular pieces.
