Lentil soup is a classic dish that is both hearty and healthy. It is made with lentils, vegetables, and spices, and can be customized to suit your taste. Some popular variations include adding sausage, bacon, or ham for a meatier flavor, or adding coconut milk for a creamier texture. Lentil soup is a great way to warm up on a cold day, and is also a great source of protein and fiber.
