Pour the dough onto a lightly floured surface. Knead it for a couple of minutes. It should be smooth and elastic. Wrap it in cling film. Let it rest at room temperature for at least 1 hour.
Divide the dough into even portions. Start stretching the dough using your fingers and the palms of your hand. Use a rolling pin in the end (the dough is a bit tough so apply some force). Roll out the dough thinly into a round shape.
Add a dough circle and cook it on one side for about 2 minutes. Brush the top lightly with extra sunflower oil when the surface starts to bubble up.
Remove the cooked flatbread from the pan onto a plate. Brush the pan with a little sunflower oil and bake the rest of the chapati doughs like the first one. Then fold the chapati up in half and again in half. Serve lukewarm.
