Add olive oil to a pot and let heat on medium.
Add onion, carrot, and pepper. Cook until onion is translucent, about 3-4 minutes. Add minced garlic and saute for another minute.
Add flour and stir until juices have been soaked up.
Add bone broth and let cook until it starts to boil.
For the sausage, you can do it a couple different ways. I like to slice up the links and throw them in the air fryer for a couple minutes. You could also just slice them up and throw them in with the bone broth while its boiling. If you are using ground sausage, saute it in a pan until cooked thoroughly.
Add tortellini and let boil until soft.
Add milk, salt, pepper, Italian seasoning, spinach, and sausage if you haven't yet already.
Stir until combined and spinach starts to wilt.
Optional: Top with fresh grated parmesan or mozzarella.
