Add the ground pork to a large soup pot. Sauté over medium-high heat, stirring occasionally, for 7-10 minutes, or until the meat is browned all over.
Add the onion and celery to the pot and cook for 4-5 minutes.
Add the flour and garlic and cook for a minute, stirring constantly.
Slowly add the chicken broth and stir until the flour has completely dissolved.
Add the canned tomatoes and Italian seasoning to the pot. Increase the heat to high and bring the soup to a gentle boil.
Once it’s boiling, add the tortellini and reduce the heat so it’s gently simmering. Cook for 5 minutes.
Stir in the cream and cook for another 5 minutes.
Stir in the spinach and season with salt & pepper to taste.
