Heat olive oil in your big pot and add the cut-up chicken pieces to cook them nicely.
Cook chicken for 6 to 7 minutes until it turns golden brown and is cooked through completely.
Add the minced garlic and cook it for 1 minute until it smells really good and fragrant.
Pour the chicken broth in and add the Italian seasoning, salt, and black pepper to the pot.
Make it boil, then turn the heat down to medium and let everything simmer together gently here.
Add tortellini and cook for 7 to 9 minutes until they all float up to the top of the soup.
Stir in the cream and spinach, cooking for 2 minutes until the spinach gets soft and wilted nicely.
Take off the heat and mix in the Parmesan cheese, then taste and add more salt if needed.
Scoop the hot soup into bowls and put extra cheese and basil on top if you want.
