This is an adaptation of the famous Russian salad Olivie. Olivie once was a huge tradition for every celebration in the Soviet Union; now we make it as a meal or for holiday occasions. My friends love this salad because it has many ingredients and come out either as a side or hearty addition to any potluck. The amount of every ingredient is adjustable. I prefer to use turkey as a meat. Chicken works well too. Spring onion and parsley are optional but I like the flavor they add to the mix. I also prefer light or low fat Mayonnaise, but it does not matter which one.
