Zuppa Toscana Copycat (Sausage, Potato, and Kale Soup) From The Food Charlatan. Zuppa Toscana is a rich and creamy, soul-satisfying soup made with Italian sausage, potatoes, and hearty kale. It’s a copycat recipe of the famous soup at Olive Garden. I could eat this stuff for days! #zuppatoscana #soup #easy
