Mix the flour, salt, yeast and oil in a large bowl and add enough water to make a soft, but not sloppy, dough. Knead well. Put into a lightly oiled bowl to rise for 1 hr until doubled in size.
Divide the dough into 8 pieces, about 250g each, and use a rolling pin to flatten each one into a circle, 15cm in diameter, about 1cm thick. Then leave the pieces on a lightly floured baking tray to prove for 5 mins. Heat a large frying pan to a medium heat and dry-fry each piece until browned on both sides, about 5 mins in total. Set aside to cool slightly before serving.
