This is my "go to" potato salad that I've been making for quite some time. It's the one my husband always requests because it's so tasty and because it contains no mayonnaise. For those who do and don't enjoy mayonnaise, this potato salad is sure to please with it's definite Mediterranean flavors. This recipe originally came from a high-end grocer, J. Bildner and Sons in back bay Boston. I've tweaked a bit from the original recipe.
