Boston Lettuce Salad with Beets and Yogurt Dressing

Right now, here in Dallas, there are some nights that it's simply too hot to cook. If you've raosted a few beets in advance, this tasty salad is a cinch to prepare. And it's complex enough with tanginess, crunch and the sweet earthy flavor of the beets, that a large portion makes a perfectly satisfying summer meal.

Boston Lettuce Salad with Beets and Yogurt Dressing
From Martha Stewart's Everyday Food.
Makes 4 servings.

3/4 pound beets (2 large or 8 small), trimmed
3 tablespoons extra-virgin olive oil
Coarse salt and ground pepper
1/2 cup Greek yogurt (full-fat or 2 percent)
2 teaspoons sherry vinegar
1 head Boston lettuce
2 tablespoons fresh tarragon
1/2 cup unsalted pistachios, toasted

Preheat oven to 450°. Place beets in a 12-inch square piece of foil. Drizzle with 1 tablespoon oil and season with salt and pepper; fold foil into a packet. Roast until beets are easily pierced with a paring knife, 30 to 45 minutes. When cool enough to handle, peel beets and cut into wedges.

Whisk together yogurt, vinegar, and 2 tablespoons oil; season dressing with salt and pepper. Thin as desired with 1 to 2 tablespoons water.

Divide lettuce among plates and top with beets, tarragon, pistachios, and dressing. Serve immediately.
