William's Pancetta Wrapped Salmon with Balsamic Lentils

Thanks to William, http://theboydonefood.blogspot.com/2007/03/first-past-post-or-not.html this was our dinner last night. It was absolutely to die for, even my mother, who thought she wasn't to fond of lentils, scoffed it and asked for seconds.
I added asparagus because I still had some that had to be used and it worked well.
