Pat chocolate dough into rectangle shape. Place between sheets of Reynolds Parchment Paper paper. Roll to 10x6-inch rectangle, patting into shape with fingers as needed to retain rectangle shape. Repeat with green dough; remove top sheet of parchment paper. Remove top sheet of parchment paper from chocolate dough. Turn upside down over green dough, pressing firmly; remove parchment paper. With sharp knife or pizza cutter, cut lengthwise into 3 equal strips. Stack strips so you have 1 long rectangle, about 1 1/2 inches high and 2 inches wide, pressing firmly. Wrap in plastic wrap; refrigerate 1 hour.
