Brown the ground sausage in a large skillet. Drain off any excess grease and allow the sausage to cool slightly.
Place the Italian sausage, onion, carrots, celery, garlic, salt, pepper, crushed tomatoes and chicken broth in a crock pot.
Cover and cook on low for 6-8 hours or on high for 3-4 hours.
Whisk together the heavy whipping cream and cornstarch together in a small bowl. Then stir this mixture, tortellini and chopped spinach into the crock pot. Cover and cook on high for 20-30 minutes until the tortellini is tender and the soup is thickened.
Serve warm and enjoy!
