Toscana means Tuscan, and Zuppa means soup, so it literally means Tuscan soup. It is the most popular soup at the Olive Garden Restaurant. It is made with potatoes, Italian sausage, bacon, and kale, along with onion, garlic, and oregano, all cooked in chicken broth with parmesan cheese melted on top. I make mine without bacon most of the time, but sometimes I do add it. Either way, it is delicious.
