In a large saucepan, heat the olive oil until shimmering. Add the bell pepper, onion and garlic and cook over moderately high heat until the vegetables are just beginning to brown, about 4 minutes. Add the ham, cumin, coriander and chipotle and cook until the ham is lightly browned, about 3 minutes longer. Add the black beans, hominy and stock and bring to a boil. Simmer the stew over moderate heat until slightly thickened, about 10 minutes.
