ARUGULA, POTATO, AND GREEN BEAN SALAD WITH CREAMY WALNUT DRESSING image

Number Of Ingredients 10

1 ounce walnuts (about 1/3 cup)
2 tablespoons white-wine vinegar
2 tablespoons nonfat plain yogurt
1 teaspoon Dijon mustard
1 teaspoon coarse salt
Freshly ground pepper
2 tablespoons walnut oil
1 1/2 pounds fingerling potatoes, cut crosswise into 1/2-inch-thick rounds
6 ounces haricots verts or other green beans, trimmed
3 ounces baby arugula

Steps:

Preheat oven to 375 degrees. Place walnuts on a rimmed baking sheet. Toast in oven until fragrant, about 8 minutes. Let cool slightly. Finely chop, and set aside. Whisk together vinegar, yogurt, mustard, 1/2 teaspoon salt, and the toasted nuts in a small bowl; season with pepper. Add oil in a slow, steady stream, whisking until emulsified. Set dressing aside. Bring a medium saucepan of water to a boil. Add potatoes, and cook until tender, about 10 minutes. Using a slotted spoon, transfer potatoes to a colander to drain. Set aside. Prepare an ice-water bath; set aside. Return pan of water to a boil. Add green beans, and cook until tender and bright green, about 4 minutes. Using a slotted spoon, transfer to ice-water bath to stop the cooking. Transfer to a cutting board, and cut into 2-inch pieces. Arrange arugula, potatoes, and green beans on a platter. Season with remaining 1/2 teaspoon salt and 1/4 teaspoon pepper. Drizzle with dressing; toss to coat.
