Lentil soup is a flavorful dish made with lentils, celery, carrots, onion, garlic & seasonings for a delicious bowl of soup for a cozy night. We love this lentil soup recipe because it’s simple to throw together and has all the best flavors! We like to make this with a loaf of sourdough bread, butternut squash salad, and twix cheesecake for dessert.
