Brush each sheet with melted butter, layer another sheet on top, repeat, and then cut each sheet into four lengthways, then turn cut sides to face you.
Dollop a little of the cheese mixture onto the corner of each strip, fold over and form a triangle. Brush with more butter and fold again. Repeat two more times. You will have a neat little triangle with no open edges. Cut and set onto lined baking tray. Repeat until all mixture is used. Brush each triangle again with any remaining butter.
Bake for 10-15 minutes until golden and crispy.
