Distinguished from other lentils by their mottled khaki color, regular lentils have a mild, somewhat earthy flavor. Commonly used to make hearty soups, stews, and side dishes to serve along with grains and pastas, this variety holds its shape well after cooking. Still, these tender beans are also easily mashed, which is why they have long been associated with making vegetarian meat loaf and burgers. Nutrition-wise, lentils are rich in complex carbohydrates, a nutrient that boosts the metabolism and helps the body to burn fat. Besides, they are an excellent source of fiber, which can help reduce cholesterol levels. In fact, the health benefits of eating them are numerous, and can help improve heart health.
