- Heat olive oil in a large, heavy soup pot over medium heat. Add the diced onion, pepper, celery, carrot, salt, and pepper. Saute until veggies are soft, 6-8 minutes.
- Add the minced garlic and diced sausage and saute until garlic is fragrant and sausage is starting to brown, about 3 minutes.
- Add the beef broth, refried beans, chili powder, and cumin. Stir until well combined. Lastly, add in the black beans.
- Bring soup to a boil and then reduce heat to low and simmer for 15-20 minutes. Adjust seasoning to taste. Enjoy!
