In a large mixing bowl, combine the all-purpose flour and salt.
Create a well in the centre of the flour mixture.
In a separate bowl, whisk together the water, olive oil, and vinegar (if using).
Gradually pour the wet mixture into the well of the flour mixture.
Mix the flour and wet ingredients until a shaggy dough forms.
Transfer the dough onto a floured work surface and knead for 10-15 minutes until smooth and elastic.
Shape the dough into a ball and lightly coat it with olive oil.
Place the dough ball back into the mixing bowl, cover it with a kitchen towel, and let it rest at room temperature for at least 1 hour.
Divide the rested dough into smaller portions (6-8 pieces) and shape them into balls.
On a floured surface, roll out each dough ball into thin sheets, aiming for a thickness of 1/16 to 1/8 inch.
Optional: Stretch the rolled dough by hand for an even thinner texture.
Brush each layer with olive oil or melted butter to prevent sticking.
Stack the rolled-out sheets, lightly dusting each layer with flour.
