This is another recipe that my family has been making for ages. I grew up eating this before I ever had the kind with mayonnaise (which I also happen to love) I have approximated some of the amounts of the ingredients simply because the cooks need to find the right amount by tasting as they go along. Everyone who has tried my family's version has raved, being Italian or non. This also develops more flavor when it sits for a few hours or overnight. Just stir well before serving. One last thing... although I normally use red wine vinegar, I also use Balsamic, but balsamic can give the salad a brownish color that may not be as visibly pleasing, but still tastes wonderful!! Please note: This salad is intended to be slightly tart. Be careful when adding the vinegar. You may not want to use the full amount. Add gradually according to your taste.
