If you’re using link sausage, remove the casings and crumble into a large soup pot. To remove the casings, you can use a sharp knife to cut a slit down one side of the sausage and then peel back the casing. Chop onion and add to pot with garlic and a drizzle of olive oil. Continue cooking until onions are translucent and your sausage is cooked. Your house will smell heavenly. Add tomatoes, tomato sauce, cider, 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.
