This is a delicious creamy lentil soup from Nepal. It's quite flavorful as well as being healthy. There are countless variations of this soup recipe, which differ in the lentils (some use red, some use yellow, etc) and spices used which primarily reflects the region where the recipe originated. It easily adapts to recipe substitutions, so feel free to increase, decrease, omit or add ingredients that suit your taste preferences, with the exception of the lentils, of course. Because what would lentil soup be without lentils?
