Remove dough from bowl and place onto a floured work surface. Lightly pat into a flat shape about 1 inch thick. Use a knife to cut dough into 8 pieces.
Form each piece into a small round ball with a smooth top, pulling dough from the sides and tucking the ends underneath the bottom.
Cover dough balls with lightly oiled plastic wrap and let rest for 30 minutes.
Sprinkle a small amount of flour on a work surface and top of a dough ball; gently pat dough ball flat with your fingers, forming a flat, round bread about 1/4 inch thick. Let dough round rest for 5 minutes.
Repeat with remaining dough balls.
