Even though folding cheese sambousek can be a bit tricky, the prospect of doing so does not have to be daunting. After cutting the filo pastry into rectangles, place a small amount of filling (about 1-2 tbsp) in the corner of them. Fold this corner down so you get a triangle shape with filling in it. Now keep folding this filling-stuffed triangle down the length of the rectangle to create more layers of filo pastry. Use a beaten egg to close it and brush the exterior.
