Put one can of the black beans in a food processor with the chipotle and adobo. Process until smooth and set aside.
Heat the oil in a medium pot over medium-high heat. Add the onion and cook for about 3 minutes. Then add the red bell pepper, garlic and carrots and cook for about 3 more minutes.
Reduce the heat to medium. Add the cumin, chili powder and oregano and cook for 30 seconds. Add all the beans, brown sugar and the tomato purée. Cook for 5 minutes.
Add the salt, pepper and water. Cook for 15 minutes more, stirring occasionally. Add the fresh cilantro and serve.
