In a small bowl, mix the minced scallions with 1 tablespoon of the sesame oil and the salt. Cut the dough in half. On a work surface, roll out each piece of dough to a 10-by-6-inch rectangle. Spread the scallion mixture over the dough, leaving a 1/2-inch border all around. Starting at a long edge, roll up each piece of dough and pinch to seal. Coil each roll of dough into a round and tuck the end under the coil. Cover and let stand for 15 minutes.
