This soup is delicious, nutritious and colorful with a good source of protein and dietary fiber. Brown, red, yellow or black lentils can be used depending on taste. This hearty soup can easily be a vegetarian soup, just by removing the meat from it. I chose to use lamb meat in this dish just to add some flavor. I am going to be making lentil and quinoa soup all winter long, serving to my family when they come over. It can also be frozen in small portions for lunch or dinner as needed.
