Combine all the ingredients except the puff pastry and milk.
Mix until well combined.
Working with one sheet of pastry at a time and starting on the left hand edge, place a large sausage of the meat mixture the full length of the pastry (2 inch wide, 1 high).
Picking up the edge with the sausage on it, roll the pastry until you reach the other end.
Press the pastry down.
Using a sharp knife, cut the log into 7 sausage rolls.
Freeze or Cook.
Bake immediately after brushing with milk at 200 degrees for approx 20 minutes or until pastry is golden.
Freeze: put the rolls well spaced on a baking tray until solid then move to containers. Bake from the freezer at 210 degrees, brushing first with milk. Bake for approx 20-25 minutes, or until the pastry is golden.
