Lentils du Puy are a French variety with a speckled green color and a firm, nutty texture even when fully cooked. In this recipe we dress Puy lentils, carrots and tangy-sweet raisins (or chopped dried apricots) with a harissa- and honey-spiked lemon vinaigrette. The lentils require about 20 minutes of simmering; use that time to prep the other ingredients for the salad. Served at room temperature or even lightly chilled, this is a great side to roasted or grilled meats of any sort, but also makes a terrific light vegetarian main.
