A friend of mine always makes it with a thick cheese or white sauce and puts roast chicken and spinach in it. You could also add corn, or zucchini or roasted pumpkin or all of them!!! You could do it with a can of soup or any other kind of soup (thicker rather than thinner).
Pretty well you just get a cob. Chop the top off pull the insides out, leaving a little bit on the walls and base, and break into pieces to dip and the crisp it up in the oven. Once you've crisped it up pour in you sauce/soup and serve
Yummy!!!
