A year ago, went to the city of Omsk to his girlfriend. And in some restaurant tried this salad, it's actually why I called. Very well, we liked it. Not very expensive (in the home, so the price was decent), very simple in execution, and most importantly delicious!
The recipe was onions, but I replaced it with green. With mushrooms drain the marinade. All mix and fill with sour cream + mayonnaise. Season with salt and pepper. As you can see nothing complicated, but delicious!
