In a dutch oven or large pot, saute onion, carrot, sweet potato, celery, pepper, and garlic in olive oil over medium-high heat until vegetables just begin to soften.
Reduce heat to medium and add diced tomatoes, black beans, tomato sauce, water, seasonings, parsley, and salt and pepper to taste. Cover and let chili simmer over medium heat, stirring occasionally until vegetables are tender. Enjoy chili hot!
