Brush a baking sheet with olive oil. On a generously floured work surface, roll 1 piece of the dough into a 14-by-7 1/2-inch rectangle. With a pizza cutter or sharp knife, cut the dough into five14-inch-long strips. Transfer the strips to the baking sheet and brush lightly with olive oil. Sprinkle with salt and bake until browned and crisp, about 10 minutes. Transfer to a rack to cool. Repeat with the remaining dough.
