Vegetable Cabbage Soup

In a large pot (or dutch oven) over medium heat, heat olive oil. Add onion, carrots, and celery, and season with salt, pepper, and chili powder. Cook, stirring often, until vegetables are soft, 5 to 6 minutes. Stir in beans, garlic, and thyme and cook until garlic is fragrant, about 30 seconds. Add broth and water, and bring to a simmer.  Stir in tomatoes and cabbage and simmer until cabbage is wilted, about 6 minutes.
