Runza

A runza is a yeast dough bread pocket with a filling consisting of ground beef, cabbage or sauerkraut, onions, and seasonings. Runzas can be baked into various shapes such as a half-moon, a rectangle, a round (bun), a square, or a triangle. The runzas sold by the Runza restaurant chain are rectangular while many of the bierocks sold in Kansas are round buns. (Wikipedia)
