Instructions: To make the filling, place the half-fat spread, flour, milk and parsley in a saucepan and whisk continuously over a moderate heat until the sauce thickens. Cook gently for 1 minute. Add the chopped eggs, flaked fish, mushrooms, and seasoning to taste. Remove the pan from the heat and set aside to cool.

Preheat the oven to Gas Mark 7/220 C/425 F.

Roll out the pastry on a lightly floured surface to a 30cm (12 inch)

square. Lift onto a lightly greased baking sheet.

Place the filling in a 10cm (4-inch) wide strip down the centre of the pastry, leaving approximately 4cm (1 1/2 inches) at each end. Brush the pastry edges with beaten egg and cut 2.5cm (1-inch) wide strips from the filling to the edge on both sides. Fold the strips over the filling alternately to form a plait making sure that the filling is completely covered and the ends tucked under.

Brush the pastry with beaten egg and bake in the oven for 20-25 minutes until golden brown. Serve hot, garnished with lemon slices and parsley.
