Tostones are a popular Venezuelan side dish made from green plantains. The plantains are sliced, fried until golden brown, and then flattened with a press or a heavy object. The flattened plantains are then fried again until crispy. Tostones are typically served as a side dish or as a base for various toppings such as guacamole, cheese, or salsa. They are loved for their crispy texture and versatility.
