The most “traditional” Greek recipe for tuna salad is the one I recall from my youth: tuna mixed with all sorts of chopped vegetables and served with a blanket of…yes…mayonnaise! Not so this dish. Here is a perfect Mediterranean Diet recipe for one of the world’s most popular lunch items, canned tuna. Add a little extra virgin Greek olive oil, fresh and dried Greek herbs, and capers, preferably from Santorini, and, voila, a classic is born.
