In a large pot or Dutch oven brown the Italian sausage over medium heat, breaking up as you go.
Once the sausage is cooked through drain off any grease.
Add the onion, celery and garlic to the pot and sauté for 4-5 minutes until the onion has softened.
Add the drained tomatoes, spiced and broth. Stir well and bring the soup to a simmer.
Once the soup is simmering add the tortellini and cook an additional 3-4 minutes, according to the tortellini packaging.
Once the tortellini is floating and is tender, stir in the heavy whipping cream and the spinach. It may be necessary to add the spinach one handful at a time.
Stir in the parmesan, add salt and pepper to taste.
Notes
I used a 9 ounce package of Taste Republic Gluten Free Cheese Tortellini
