Fold bottom corner over filling to cover, then fold over right & left corners. Roll over once to enclose filling. Brush sides & top of triangle with flour & water mixture. Fold over to seal. Cover filled rolls with a damp cloth while preparing the rest of the rolls. Place a non-stick frying pan over medium heat. Add 1 to 2 tb oil. Add rolls two at a time & cook for 2 minutes on each side, or till golden brown. Transfer to a heat proof dish & keep warm in a 90ºC oven while cooking remaining rolls.
