Cut the mushrooms into slices, diced onions and fry in sunflower oil until cooked (but not fried). Then you need to make the oil with mushrooms glass. I put the mushrooms in a colander and put a plate on the bottom.
Cut Bulgarian pepper into cubes.
Pickles are also cut into cubes. Cucumber to taste, you can not add, then the taste of the salad will be a little sweet.
Finely chop the greens. Mix all the ingredients, add mayonnaise and mix!
