""Ground beef, onions, and cabbage wrapped in bread dough and then baked. Can be made smaller and served as an appetizer. We called these sandwiches Bierocks. I assume they must have originated in Europe and each country has a name for them. I have heard them called Runzas also. They really are simple. I have found that I cannot substitute anything for the MSG. They just lose the flavor. If your ground beef is too lean, these tend to be dry. I sometimes add cheese to them to offset this problem. I have also added fennel seed, about 1 teaspoon, although the recipe does not call for it."..."
