In a large pot over medium heat, add some olive oil.
Brown the garlic and onions. Then add in the sausage and allow to brown.
Stir in the tomatoes, zucchini, broth, and seasonings, stirring to combine.
Allow to simmer for 40 minutes.
While the soup is simmering, in a separate pot, bring water to a boil and prepare the Diltalini pasta.
Drain the pasta and allow to cool.
When ready to serve, add the pasta and top with some freshly grated Parmesan cheese.
