If you're using link sausage, remove the casings and crumble into a large soup pot.
Begin cooking sausage over medium heat, stirring frequently. If your sausage is pretty fatty, you'll want to drain it when it's about halfway cooked. Meanwhile, chop onions and garlic and add to the sausage. Continue cooking until onions are translucent and your sausage is cooked.
Add tomatoes, tomato sauce, juice, water, chicken broth, carrots, oregano, and basil. Cover and simmer for 1/2 hour. Add parsley and zucchini and simmer for another 15 minutes or so.
Add the tortellini and cook until tender, and then serve with bread and freshly-grated Parmesan.
