Cut the pastry into rectangles or squares. I usually do about 5 inches x 3 inches.
Load a pepper and sliced mozzarella onto one half, leaving a centimetre around the edges.
Brush milk (or egg) around the edges to enable a good seal. Fold over pastry, and use your thumb or a fork to crimp the edges
Brush milk (or egg) over entire parcel and put them on a (slightly oiled or use tin foil) baking tray in the oven on 180 degrees for approximately 25-30 minutes. Serve alone or with green salad.
