This is a recipe that I made up, after being inspired by a tuna salad niçoise that I had ordered at a restaurant that had boiled potatoes in it. The tuna I ordered up was fresh tuna, done medium rare, but I used canned tuna... and it still tastes very fancy. Really, the traditional salad is served room temperature, but this modification is great ice cold out of the fridge for up to a week -- when all of the flavors have married together.
3/4 sack of Yukon Gold potatoes
1 large can albacore tuna, drained
large bunch fresh green beans, ends trimmed and cut in half
1/2 finely diced red onion
two handfuls rough chopped arugula
3 cloves minced garlic
handful minced fresh dill
1/2 bottle of champagne vinaigrette, or Newman's Light Honey Mustard dressing
juice of 1 lemon, plus plenty of grated lemon zest
plenty of salt, and pepper
Dice and boil the potatoes, steam the beans briefly and rinse all with cold water. Then just combine the rest to taste. I used some of that fancy champagne vinaigrette dressing the first time, but at 20 grams of fat per serving, I tried the Newman's light dressing (honey mustard) the second time, and I think I liked it even better. Also, if you don't want your salad to bite you back (although the flavors mellow a lot in the fridge) quite so much, you can use less garlic -- or substitute garlic powder. But I'm convinced that anything so potent has to have magical powers (and not just the power to make your date disappear,) so of course I'll stick with the raw garlic.
And I wouldn't skimp on the lemon or zest -- that's what makes this such a refreshingly crisp summer salad.
