Slice sausage and brown in the pot. Add celery and cook for 10 minutes. Add onions, tomatoes, garlic, spices and dried herbs and sugar. Cover and simmer for 20 minutes. Add zucchini and green pepper. Add water and wine (if using). Cover and simmer until zucchini is falling apart and pepper is soft. More water may need to be added as the soup can get very thick. The more this cooks, the better it tastes!
