Potato salad in summer: It's an obvious choice that delivers year after year. (It is also a friendship based on an appreciation for carbs, which I totally get.) I wanted to shake things up a bit by turning potato salad into a fuller meal -- that is, not the kind where I eat handfuls of warm potatoes tossed in vinaigrette straight from the mixing bowl.

I swapped some of the potatoes for steamed zucchini and tossed everything in a salad dressing made with canned tuna. The result is a very creamy potato salad, full of briny and salty flavor, fresh summer vegetables, and a touch of tuna for good measure.

Provençal Potato Salad with Tuna Dressing

Serves 4

3 Yukon Gold potatoes (about 1 1/4 pounds), peeled and quartered
2 zucchini (about 8 ounces), halved lengthwise and sliced 1/2-inch thick
One (5-ounce) can tuna in oil
2 tablespoons Greek yogurt or sour cream
1 tablespoon capers
1 small garlic clove
1 tablespoon red wine vinegar
2 tablespoons olive oil
Kosher salt and freshly ground black pepper
1/4 medium red onion, chopped
2 plum tomatoes, cut into 1-inch chunks
1/2 cup olives (I used Niçoise), chopped
1/4 cup torn basil leaves

As a freelance food writer and cook, I first wrote this style of recipe as a column on my blog, The Wright Recipes, as an excuse to cook good food for my friends in a quick and simple way. 

Twenty-Dollar, Twenty-Minute™ Meals grew into a cookbook that was published by Workman in May 2013. The recipes found here are original, made especially for Food52 to once again celebrate simple food with friends.
