1. In a large pot over medium high heat sauté garlic, onion, and celery in olive oil for 3-5 minutes until onions are translucent.
2. Add the sausage (casing removed) and sauté until cooked through, breaking into little pieces with your spatula.
3. Add the rest of the ingredients (besides the parmesan); bring to a boil and cover and simmer for 5 minutes - enjoy with parmesan on top!
