Set the Instant Pot to saute and heat the olive oil. Add the onion, carrots, and celery. Sauté for 5-7 minutes, or until vegetables are softened. Add the sausage and cook until done.

Stir in the garlic and cook for 1 minute, until fragrant.

Add the diced tomatoes (with their juices), chicken or vegetable broth, basil, oregano, and red pepper flakes (if using). Bring the mixture to a boil.

Set it to slow cook at this point at least 10 minutes until the vegetables are done. You can leave it here for a few hours if you want. I like to slow cook it.

Set it back to saute. Once it is boiling add the tortellini and cook as directed.

Add the spinach or kale, stirring until wilted (1-2 minutes).

Stir in the heavy cream and heat through. Taste and adjust seasoning with salt and pepper.

Serve hot, topped with grated Parmesan cheese. Enjoy with crusty bread or sweet rolls on the side!
