A delicious and hearty salad will allow you to eat well for breakfast or lunch, it can become a full dinner. The main thing is to choose a good herring.
Cut herring into small pieces, cheese into cubes, fry quarters of mushrooms in butter.
Cucumbers cut into cubes, onions finely chopped, combine all the ingredients. Add pepper. I did not salt the salad, there are enough salty ingredients in it.
Add chopped dill, drizzle with olive oil and serve. You can fill the salad with sour cream.
