Divide each loaf of thawed bread dough into 5 equal pieces. Place on a lightly greased baking sheet. Cover and let dough rise in a warm place until nearly doubled in size (about 30 minutes).
Meanwhile, in a large skillet, cook ground beef or sausage until meat is brown. Drain well.
In a large covered saucepan, cook cabbage and onion in the boiling water for 5 to 7 minutes or until crisp-tender. Drain thoroughly; return to pan.
Add meat, Worcestershire sauce, and salt to cabbage mixture.
On a lightly floured surface, roll each piece of bread dough to form a 6-inch square. Place a generous 1/3 cup of meat mixture in center of each square of dough. Moisten edges of dough with water. Bring each corner in over center forming a bundle; pinch edges to seal. Place on lightly greased baking sheets. (Cover one sheet with plastic wrap and refrigerate it while the other bakes.)
Bake in a 400 degree F oven for 14 to 16 minutes or until golden.
Remove from oven and brush with butter. Serve warm. Makes 10 servings.
