Unroll the sheets of filo pastry and place them all, one on top of the other, on a work surface.
Brush the top sheet of pastry with beaten egg and then spread over the mushroom mixture to within 4cm (1½in) of the edges.
Fold the short ends inwards a little to meet the mushroom mixture and then, starting with a long edge, roll up the pastry fairly tightly like you would a Swiss roll, keeping the mushrooms in place as you roll.
Place the strudel seam-side down on the parchment paper and brush it all over with the remaining beaten egg.
Bake for 20-25 minutes until crisp and golden brown.
Allow to cool for a few minutes before carefully placing on a chopping board.
Cut the strudel into thick slices and arrange on warmed plates. Drizzle some sauce beside it and serve with some mixed salad leaves.
For the madeira wine sauce
Heat a heavy based saucepan, add the Madeira Wine and reduce by half.
