I must also point out that the dressing for this salad is amazing. It is a classic French dressing with shallots, white wine vinegar, and grainy mustard. We had a little extra left over, and I used it to dress a salad we made later in the week. It was a perfect complement for this salad, comprised of butter leaf lettuce, colorful tomatoes, wax beans, and feta cheese.
But, back to the point, this potato and tuna salad is amazing. It's a complete meal on it's own, and would also be beautiful as part of a larger spread. It is fresh and bursting with flavor, especially when you use the farm-fresh produce that is so abundant this time of year! My salad included farmer's market potatoes and tomatoes, and basil from my own back porch. Make sure to buy chunk light tuna, especially if you can find it packed in olive oil instead of water. It gives it the European flair that this salad deserves. Sit on your porch with a little chilled french wine, and you'll almost be able to taste the French countryside!
