GARNISH: corn, chopped scallions, shredded Cheddar or Monterey jack cheese, or a combination, optional.
In a Dutch oven or 4-5 qt saucepan, heat oil. Saute garlic, green pepper, celery, onion, carrot, and zucchini until crisp/tender, about 3 minutes.
As mixture cooks, stir in remaining ingredients. Bring to a boil over high heat, then reduce heat to medium. Cover and cook until heated through, about 5 minutes.
Top each serving with a garnish, if desired. If you wish, set under broiler to melt cheese.
