Bierocks and Runzas both refer to the same handheld sandwich concept - a hearty domed yeast bread pocket filled with a warm, savory blend of beef, cabbage, and onions. "Bierock" is more commonly used in parts of Kansas and the Dakotas for these round handhelds, while Nebraskans favor the term "runza" for the typically rectangular shape made famous by Runza restaurants.
