Key Ingredients

Brown lentils are easy to find. Lentils have an earthy, neutral flavor when they are cooked. Just be sure to give them a rinse before adding them to the Instant Pot.

Sausages add protein and flavor to the soup and make it so hearty. You can use pre-cooked or uncooked sausages; I prefer to use Italian flavored pork or beef sausages in this recipes.

Chopped veggies including onion, celery, and carrots add more texture and nutrition.
