Add the chopped celery, green pepper, sugar, salt, basil, oregano, pepper and tomatoes (with their juice). Stir well to combine. Cover the Dutch oven and simmer the soup for one hour, allowing the flavors to meld together and the vegetables to soften.

Editor’s Tip: Stir occasionally to prevent sticking and to ensure that the soup cooks evenly.

Step 3: Add zucchini
