Spray a large saucepan or Dutch oven with a few sprays of the oil spray. Add onion and saute over medium-high heat until tender. Add chipotles, sausage, seasonings, beans, tomatoes, chocolate, and wine. Bring to a boil over high heat and then reduce the heat to a simmer. Cover and let simmer for 30 to 40 minutes. Stir in cilantro and cheese just until cheese is melted. Serve immediately.
