1Heat oven to 450°F. Spray cookie sheet with cooking spray. Unroll dough on lightly floured work surface. Cut into 3x1/2-inch strips; with hands, roll each strip into rope about 5 inches long. Tie each strip into a knot. Place on cookie sheet.
2In 4-quart saucepan, heat 5 cups water and the baking soda to boiling. Drop dough knots, 6 at a time, into boiling water. Cook 30 seconds or until dough looks slightly puffy and dimpled. Using slotted spoon, remove knots from water; return to cookie sheet; place about 1/2 inch apart. Brush dough with egg; sprinkle with salt.
3Bake 10 to 12 minutes or until well browned. Immediately remove to cooling rack. Cool 5 minutes. Serve pretzel bites warm with queso dip.
