Nope, not the kind of grilled cheese you are thinking of, my friends.
I had seen this a while back in a cook book I picked up cheap at a conference I was at in April.
The book is called "Sizzle: Sensational Barbecue Food." So far I have not tried too much from it, but there are some interesting dishes.
First up, something the author called Pots of Gold. Basically you take a hunk of yummy, creamy cheese and use the grill to make a sort-of fondue. (Pictures with the recipe... follow the link!)
It was quite the lovely mid-afternoon snack on a warm Sunday. Enjoy it with a white wine or a cold beer.
