Thaw the pastry and roll out to measure 12 x 14 inches. Cut 4 squares in each sheet. Spread each with some of the cheese. "Squush" the breast into shape and place on the pastry dough. Fold the pastry like an envelope and seal seams with water. Pinch to seal. Take remaining dough and cut into 1/4' strips. Twist two strips together and "tie up" the package. Add a festive dough-bow. Brush with melted butter. Bake at 350 degrees until brown, about 30 to 35 minutes.
