Spinach, Sausage and Tortellini Soup in the Slow Cooker

I made this for our "Souper Bowl" contest at work and got a lot of compliments - I just like how easy it is to make!

Spinach, Sausage and Tortellini Soup
(4 – 6 servings)

6 cups of chicken broth
1 tablespoon olive oil
1 to 2 tablespoons of minced garlic
½ cup of diced onion
1 package of fresh three cheese tortellini
3 cups of fresh baby spinach
½ teaspoon of dried oregano
½ teaspoon of dried basil
½ teaspoon of dried thyme
1 bay leaf
1.5 cups of diced chicken sausage (this is about 1 package already cooked)
1 can of great northern beans
1 can of diced tomatoes

Grated Parmesan cheese for serving.

Put all ingredients in the slow cooker for 5 hours on low. remove bay leaf and serve with a baguette.
