Lentil and spinach dahl is a versatile, hearty, and nourishing dish. The spices used in this recipe create nuanced layers of flavor that breathe new life into the humble ingredients. Dahl is best described as a flavorful curry or stew-like soup. It consists of legumes and, in this case, fresh leafy greens. First, the lentils are cooked until tender. The spinach follows, an aromatic base is built, everything comes together, then, before you know it, the dahl is ready. Serve it as is, with a simple swirl of yogurt, naan, or rice.
