Lightly spray 2 cookie sheets with nonstick cooking spray. To make cookies: take a small ball of dough and roll into a sausage shape a little more than 1 cm thick by 13 cm long. Curve into an "s" shape and put on cookie sheet. Repeat until all dough is used. Bake 5 minutes. Reduce heat to 350 degrees. Bake another 15 minutes or until golden brown.
