Transfer on a floured surface and knead until smooth for about 3 to 5 minutes.
Shape into a ball or roll into a long log. Divide and cut into 8 pieces, then roll each dough into balls.
Cover with a mixing bowl or tea towel to avoid drying out. Let it rest for 20 minutes.
Flatten the dough into rounds with a rolling pin to roll out into 8". About 2 to 3 mm thick.
Skillet Flatbread. Heat the skillet and brush with oil or melt butter. Place one flattened round dough and cook for about 1 to 2 minutes per side on high heat. Cook while pressing with a spatula, and flip when puffy. It's cooked when puffs up and has a golden spot.
Air fryer Flatbread. Preheat the air fryer to 400°F. Place the flattened round dough in a greased baking pan and cook at 375°F to 400°F for 1 to 1-½ minutes per side or until it puffs up. Air fryer temperature may vary.
Optional-Brush the cooked flatbreads with butter or olive if desired.
Stack the cooked flatbreads and wrap them with a tea towel to keep them warm and moist.
