Beef Tortellini Soup

1 lb beef stew meat
2 C spicy marinara or spaghetti sauce
3 C vegetable broth
2 cans 14.5 oz regular diced tomatoes
1 tsp Italian seasoning
8 oz dried tortellini pasta noodles
2 T heavy cream optional
grated parmesan cheese for serving, optional

Add stew meat, spaghetti sauce, broth, diced tomatoes and Italian seasoning to slow cooker. Cover and cook on low for seven to nine hours. Remove lid and stir (you can also break up any larger chunks of stew meat if desired). Add tortellini pasta and turn slow cooker to high, let cook for 20 to 30 minutes or until pasta is tender. To cut the acidity a bit you can stir in one to two tablespoons of cream, this is optional but does help the flavors work together nicely. Serve garnished with grated parmesan cheese or as desired.
