Gua Bao is a popular Taiwanese street food that consists of a soft, steamed bun filled with braised pork belly. The bun is typically made from wheat flour and has a fluffy texture, making it a perfect vessel for the rich and savory filling. The pork is usually marinated in a mixture of soy sauce, sugar, and spices, giving it a deep flavor. In addition to the pork, Gua Bao is often garnished with pickled mustard greens, crushed peanuts, and fresh cilantro. This combination of ingredients creates a delightful contrast of flavors and textures, making Gua Bao a beloved dish among food enthusiasts.
