Fry bacon strips in a large skillet over medium heat until crisp. With a slotted spoon, remove bacon to paper towels. Reserve 1/2 cup bacon drippings.
Place drippings in a large pot, and warm over medium heat. Fry onions until light brown. Stir in ham and chorizo. Reserve 1 cup of beans, and add the rest to the pot, along with the chipotle and garlic.
Mash the reserved beans, then add to the pot. Simmer beans until thick and soupy, about 30 minutes. (If the beans become too dry, stir in water). Remove chipotle and garlic, and serve.
