I have a real quick n easy one thats great as a last minute dip (no thought or preparation required!!!)

1 large cob
2 pks of light philly cream cheese (I use the light philly so I don't feel as guilty)
1 pkt dry french onion soup mix

Cut top off cob loaf and scoop out inside
Mix soup and philly together and put inside cob
Put lid back on and wrap in foil
Heat in oven on 180 for about 20 mins

Yum, but sooooo easy and great if you don't have time to prepare.
