The lentil is a brushy annual plant of the legume family, grown for its lens-shaped seeds. With 26% protein, lentil is the vegetable with the highest level of protein other than soybeans, and because of this it is a very important part of the diet in many parts of the world, and especially South Asia which has a large vegetarian population. Apart from a high level of proteins, lentils also contain dietary fiber, vitamin B1, and minerals. Red lentils contain a lower concentration of fiber than green lentils and Health magazine has selected lentils as one of the five healthiest foods. I hope you Enjoy this Broccoli Lentil soup recipe.
