Every country has different way to prepare this salad. We call “Russian Salad”, but we also know “Olivier” Salad assumingely originates with Belgian chef , and his recipe comes to the postSoviet Countries. Even Europe , Israel , Mongolia, and south America . Of course recipe varies country to country . They say in the original recipe salad contained , crayfish tail, veal tongue, duck, caviar, but who is going to find those? The cheapest and fastest way we are preparing this famous salad. I add beets, I liked the color of the salad become, I also used 2 eggs. Some recipes including bologna or chicken. But I never used any meat. You are welcome to create your own version. But I have never used can vegetables . They are so watery and mushy .i use frozen peas.
