Ingredients

Serves 4

　　3/4 cup lentils, picked over and rinsed

　　3/4 cup walnuts

　　1/3 cup plain dried breadcrumbs

　　3 garlic cloves, coarsely chopped

　　2 teaspoons ground cumin

　　2 teaspoons ground coriander

　　1/4 to 1/2 teaspoon red pepper flakes

　　Coarse salt and fresh ground pepper

　　4 tablespoons olive oil

　　1 large egg

　　Yogurt-Cilantro Sauce, for serving (optional)

　　

Yogurt-cilantro Sauce

3/4 cup plain low-fat yogurt

　　2 tablespoons chopped fresh cilantro leaves

　　1 tablespoon fresh lemon juice

　　Coarse salt and fresh ground pepper

　　

Step 1

Preheat the oven to 350°F. Place the lentils in a small saucepan, and cover with water by 1 inch. Bring to a boil; reduce to a simmer. Cover, and cook until the lentils are tender but still holding their shape, 15 to 20 minutes. Drain well and cool.

　　

Step 2

Meanwhile, spread the walnuts on a baking sheet, and toast in the oven until fragrant and darkened, about 10 minutes. Let cool.

　　

Step 3

In a food processor, combine the walnuts, breadcrumbs, garlic, cumin, coriander, red pepper flakes, 1 1/2 teaspoons salt, and 1/4 teaspoon pepper; process until finely ground. Add the lentils and 1 tablespoon of the oil; pulse until coarsely chopped (some lentils should remain whole).

　　

Step 4

In a large bowl, whisk the egg. Add the lentil mixture; mix well. Divide into 4 equal-size parts; roll into balls, and flatten with the palm of your hand into 3/4-inch-thick patties.

　　

Step 5

Heat the remaining 3 tablespoons oil in a large nonstick skillet. Add the burgers; cook over medium-low heat until crisp and browned, turning gently with a thin-edged spatula, 8 to 10 minutes per side. Transfer to a paper-towel-lined plate to drain. Serve with yogurt-cilantro sauce, if desired.
