How about putting a carton or two of philly extra light and a packet of smoked salmon into the blender. You end up with the nicest, tastiest smoked salmon pate/mousse and take a variety of ryvitas and other low fat snack biscuits for people to eat it on.
It never fails for diet conscious friends here. I tend to put 100 grams of smoked salmon to a tub of philly.
It is such a festive dish aswell.
