Heat the oil in large pot or Dutch oven over moderate heat. Add the onion, bell pepper and carrots, cover and cook, stirring occasionally until the vegetables are soft, about 10 minutes. Add the cumin and cook, stirring, for 1 minute. Add the ground beef; raise the heat to high and cook, breaking up the meat with a spoon, until the meat is no longer pink. Stir in the tomatoes, water, chipotle and adobo sauce, oregano and salt and pepper. Simmer, partially covered, stirring from time to time, for 30 minutes. Stir in the beans and cook, partially covered, 20 minutes longer. Season, to taste, with salt and pepper.
