Refried beans are a popular dish in Mexican cuisine made from cooked and mashed pinto beans or black beans. The beans are typically cooked until soft, then mashed and fried in oil or lard, which gives them a creamy texture and rich flavor. They can be seasoned with spices, garlic, or onion to enhance their taste. Often served as a side dish, refried beans can also be used as a filling for burritos or as a topping for tacos. They are a good source of protein and fiber, making them a nutritious addition to many meals.
