For the “Tenderness” salad with champignons and chicken, it is important to properly prepare the meat. Buy small-sized chicken, so there is a higher chance that it will be natural. First defrost the frozen product in the refrigerator, then rinse and dry. The best method of heat treatment is boiling. All harmful substances go into the first broth, which, after boiling, is drained and the meat is boiled in fresh water.
