This Mediterranean salad is best if the potatoes are warm when you dress and toss the salad. We recommend that you search out good quality oil-packed tuna for this recipe. Specialty shops and delicatessens are a good source. Water-packed tuna, especially albacore, is fine, but the salad won't be quite as luscious.
This recipe is from the cookbook, One Dish Meals with The Culinary Institute of America.
