Gua bao is the famous Taiwanese braised pork belly bun. It consists of soft steamed buns filled with tender pieces of pork belly, braised in a mixture of soy sauce and red wine, generously seasoned with five-spice powder. Other essential complements include sour pickled mustard greens, chopped cilantro, and a sprinkle of lightly sweetened peanut powder.

Gua bao is one of the favorite Taiwanese snacks, usually sold by street vendors at popular Taiwanese night markets.
