Preheat the oven to 400 degrees.
Combine flour, salt, oil, and sugar in a mixing bowl.
Stir well until combined.
Follow by adding the warm water slowly.
Once you have a firm dough, knead it to give your dough an oval shape.
Divide the dough into 6 equal parts.
Cover and let it rest for 30 minutes.
Place the dough parts on your work counter and apply pressure from the top to each one, using your hands. They should be about 15 centimeters in diameter.
Grease one ball with butter, and put another one on top of the former.
Repeat until you’re out of dough.
Transfer the combined balls to a baking tray and cover.
Rest for one and a half hours.
Press the edges and form a rectangular shape.
Bake for about 30 minutes.
