Slow Cooker Sunday: A super-easy recipe for lemon and lentil soup

Need a healthy, comforting meal as we head into fall? This fresh lemon, lentil and vegetable soup is prepared in the slow cooker, making dinnertime a breeze while keeping things healthy and filling. Win-win.

Soup is one of my favorite meals to make when the cooler weather arrives. You can make a simple yet delicious soup easily with ingredients you probably already have on hand.

This soup base is made from vegetable broth, lentils and vegetables and gets a hint of bright, tart flavor from fresh lemons. I add all my ingredients to the slow cooker, and before I know it, I have a hearty and healthy lunch or dinner waiting for me.

If you are vegetarian, follow the recipe as is, but meat eaters can add diced chicken to this soup for added protein.
