Saute beef, onion and garlic, salt and lemon pepper in a large skillet over medium high heat, until beef is browned. Add cabbage, Worcestershire sauce and caraway seeds. Cook until cabbage is limp; drain liquid from mixture.
Preheat oven to 350 degrees F (175 degrees Celsius.
On a lightly floured board, roll each loaf of dough into a 12 inch circle. Cut each circle into 6 wedges. Spoon cabbage/beef filling onto center of each dough piece, dividing equally.
Pull three points of each wedge up to the center and pinch to seal. Place bierocks on a lightly greased cookie sheet. If desired, brush dough with melted butter or egg wash (1 egg white with 2 tablespoons water).
Bake in preheated oven for 30 minutes, or until golden brown. Serve hot, or wrap and freeze for heating later.
