Lentil and Barley Slowcooker Soup

This soup is easy to make and is full of ingredients that are great for you!  I usually make a large batch then freeze away several containers.  Enjoy!

1/2 lb Lentils (sorted and rinsed)
1/2 cup Barley
1 lb Carrots
2, 14oz cans Cubed tomatoes in sauce
1/2 lb Spinach or Kale
1, 15oz can Corn
1, 15oz can Sweet Peas
1/2 tsp Garlic powder
1/4 tsp Onion powder
10 cups Water
3 Tbsp Better than Bouillon Chicken Base
** Vegetable stock can be substituted for the water and chicken base**

Combine all ingredients in a slow cooker and cook on high for 4 hours.  Sprinkle soup with parmesan cheese before serving.
