Cut cabbage, onion, bell pepper, celery, and carrot into bite-sized pieces.
Heat olive oil in a pot and sauté the onion and celery.
Add the rest of the vegetables and minced garlic, and stir-fry.
Add tomatoes (or canned tomatoes), water, salt, and pepper, and bring to a boil.
Simmer over medium-low heat for 20~30 minutes until the ingredients are cooked through.
