1. Cook the Sausage: In a large pot, heat olive oil over medium heat. Add the Italian sausage and cook until browned, breaking it up into crumbles with a spoon.

6. Simmer: Reduce the heat to low and let the soup simmer for about 20 minutes or until the potatoes are tender.
7. Add Greens: Stir in the chopped kale or spinach and cook for an additional 5 minutes until the greens are wilted.
8. Add Cream: Pour in the heavy cream, stirring well to combine. Allow the soup to heat through for another 5 minutes.
9. Taste and Adjust: Taste the soup and adjust seasoning if necessary. Add more salt, pepper, or Italian seasoning as desired.
10. Serve: Ladle the soup into bowls and top with grated Parmesan cheese if desired.
