In a large pot, add the hamburger, onion, bell pepper, celery, carrot, and garlic; brown the mixture until the hamburger is no longer pink.
Drain off fat.
Add the undrained diced tomatoes, tomato sauce, water, sugar, Italian seasoning, salt, and pepper and bring to a boil.
Add the noodles, return the soup to a boil, reduce heat, and simmer until the noodles are done, about 12 minutes.

At the table let everyone add as much or as little Parmesan cheese as they desire.
Notes & Wine Advice
