Punch and knead the dough. Divide it into ten equal portions. Cover the dough with a wet cloth.
Take a portion of the dough, slightly flatten it and coat it with sesame seeds. Using a rolling pin, roll it into a 6-7 inch disc. Repeat with the remaining dough portions.

Flip and cook the other side until golden brown. Remove from the frying pan and drain. Repeat with remaining discs.
