1) Heat olive oil in large soup pot or Dutch oven. Add onion, garlic, celery, and sweet potato, and saute over medium heat for about 5 minutes. Add salt and saute 5 minutes more. Add seasonings and water, cover, and simmer about 15 minutes. 2) Add tomatoes, bell pepper, and chickpeas. Cover and simmer for about 10 minutes more, or until all the vegetables are as tender as you like them (NOTE: be careful not to cook the broccoli florets, cabbage or green beans too long - a little crunch is good). Taste to adjust seasonings and salt. Serve hot with crusty bread.
