This is a simple and fast soup that is perfect for when you want something light, but still satisfying. Although it’s super creamy, the soup doesn’t include any cream at all: you get all that texture from the pureed lentils. The tempered spices poured on top add an extra dimension of flavor, but you can skip that step if you like. I like to add a dollop of raita or plain yogurt on top for extra creaminess.
