Preheat oven to 200°C. Line two large baking trays with oven proof baking paper.   

In a large bowl combine sausage mince, sauces, cumin, salt and pepper.

Cut each piece of pastry in half.  Place a strip (like a long sausage) of mince along the centre of each pastry piece. Roll to enclose with the seam underneath. 

Cut the sausage rolls into required lengths using a sharp knife and place on baking trays.  Combine the egg and milk and whisk together.  Using a pastry brush, brush the tops of the rolls with egg and milk mixture.  Top the rolls with a sprinkle of seeds, if using. 

Bake for around 25 minutes or until golden and cooked through.  Serve warm with plenty of tomato sauce.
