Gua bao ( guàbāo. Han characters: 割包/刈包; Pe̍h-ōe-jī: koah-pau; literally: "cut bread"), also known as steamed bao, pork belly buns,, Taiwanese Hamburger, or ambiguously, bao, is a Taiwanese snack food consisting of a slice of stewed meat and other condiments sandwiched between flat steamed bread. Gua bao are the forerunner to Japanese hirata buns, due to Japan’s colonial occupation of Taiwan. The steamed bread is typically 6–8 centimetres (2.4–3.1 in) in size, semi-circular and flat in form, with a horizontal fold that, when opened, gives the appearance that it has been sliced. The traditional filling for gua bao is a slice of red-cooked porkbelly, typically dressed with stir-fried suan cai (pickled mustard greens), coriander, and ground peanuts.
The food is known colloquially in parts of Taiwan as hó͘-kā-ti (虎咬豬; "tiger bites pig") due to the mouth-like form of the bun and the contents of the filling. Gua bao are also called "Taiwanese hamburgers" due in-part to the wide variety of novel ingredients used as filling, such as fried chicken, fish, eggs, and stewed beef.
