Unroll dough on work surface; press into 12x8-inch rectangle. Cut crosswise into 16 (8-inch) strips; roll each into 11-inch rope. To shape pretzel, shape rope into a circle, overlapping dough about 2 inches from each end, leaving ends free. Take 1 end in each hand; twist once at point where dough overlaps. Lift ends over opposite side of circle. Brush each with melted butter. Sprinkle with salt. Place on cookie sheet.
