Divide dough into 8 pieces. Using your fists, stretch one piece into a 6-inch round. Alternatively, with a rolling pin, roll out on a lightly floured surface. (Keep remaining dough covered with a towel or plastic wrap.) Place on a cornmeal-dusted pizza peel or an inverted baking sheet, using enough cornmeal so that the dough slides easily. Stretch or roll a second round of dough and place beside the first.
