How to Make It
In a medium saucepan, heat the olive oil until shimmering. Add the onion, garlic, cumin and chipotle and cook over moderate heat until softened, about 5 minutes. Add the chorizo and cook, breaking up the meat into small lumps with a spoon, until lightly browned, about 5 minutes. Add the beans and their liquid along with the water and simmer until slightly thickened, about 5 minutes. Season with salt and pepper. Spoon the beans into bowls, sprinkle pork rinds on top and serve at once.
