Unroll the dough, pinch together the perforations and divide into 6 squares. Place the cheese in the center of each square. Spread the top of the cheese with mustard and sprinkle with pecans. Draw up the sides of the dough to form a bundle and pinch the dough in place. Place in a 350 degree F oven for 20 minutes or until golden brown. Cool for 10 minutes and serve.
