On a cold night, nothing sounds better than a hot bowl of soup.

And that's where your Crock-Pot comes in. Before you leave for work, you can easily gather the ingredients needed to make a delicious, hearty lentil soup and toss them into your Crock-Pot so something other than canned soup will be ready to serve as soon as you walk through the door.

This lentil soup recipe is a hearty vegetarian soup.

If you like meat in your soup, you might prefer lentil soup with beef. Start by browning a pound of cubed sirloin steak over medium-high heat in a tablespoon of oil. Then, add the cooked meat to your Crock-Pot. Stir in 4 cups beef broth, 1 cup lentils, 3/4 cups diced red peppers, 3/4 cups diced green peppers, 1/2 cup diced onions and 1/2 cup diced carrots. Season your soup with 1 teaspoon cumin, 1 teaspoon cayenne pepper, 1 teaspoon kosher salt and 1/2 teaspoon black pepper. Cover your Crock-Pot and cook for 8 hours on low heat. It's not necessary to cook the meat before adding it to your Crock-Pot in this recipe, but browning meat helps enhance the flavor of both the meat and the soup.
