Take the sausage meat out of the casings and crumble it into a skillet. Cook it over medium-high heat, stirring occasionally, until it's browned. If there's a lot of excess fat, drain most of it. Leave the sausage in the pan.

Add the garlic, chicken broth, diced tomatoes, cream, and tortellini. Cook, uncovered, stirring occasionally, for 5-7 minutes or until the tortellini is cooked and the sauce has reduced to your liking. Cooking the tortellini in the sauce helps thicken it (it releases starch).

Stir in the spinach and let it wilt. Season with salt & pepper as needed and serve with fresh parmesan sprinkled over top if using.
