I am a really bad cheat with sausage rolls - I buy gourmet sausages that sound nice and then take the sausage meat out of the casings add some breadcrumbs and put in puff pastry.

Thing is if you buy some sausages from a nice deli it is more likely you will get some actual meat in there - whereas if you buy that sausage meat in packets from the s'market I'm not quite sure what actually is in there.
