Preheat oven to 200C/ 400F/ gas mark 6. Lightly grease 2 large baking trays.
Roll the pastry (even if you have bought a ready rolled sheet of pastry you will need to roll it thinner) until it is approx 30cm x 28 cm and then cut in half lengthways. Spread 1 ½ dessertspoons of Tracklements Spiced Honey Mustard onto each rectangle of pastry.
In a bowl, mix together the sausagemeat (if using sausages snip skins and peel), parsley and onion and season.
Divide the sausagemeat into two and shape each into a long sausage shape on top of the pastry.
Brush one edge with beaten egg and then roll up. Seal and turn the rolls over so that the seam is underneath. Cut each roll into 2.5 cm lengths. Cut a small slit in the top of each roll, brush with beaten egg and pop onto the baking tray. Bake for 20-25 minutes, transfer to a cooling rack and leave to cool.
