Quick & Spicy Refried Beans

Heat oil in a large saucepan over medium heat. Add onion and cook, stirring occasionally, until softened, about 3 minutes. Add garlic, chili powder, cumin and chipotle (if using). Cook, stirring constantly, for 1 minute. Add beans and cook until heated through, 2 to 3 minutes. Remove from the heat and mash to desired consistency with a potato masher. Add water if necessary to achieve desired consistency.
