I LOVE Monte Cristo's. Ive always made them by taking left-over french toast and making a grilled ham/turkey and cheese with them. Of course this is the quick way of making them.
At the restaurant Bennigan's they serve a Monte Cristo, although it's very VERY different. They make a sandwhich with 3 slices of bread and the normal Monte Cristo filling...but they deep fry the entire sandwhich! I've tried it once and after eating a part of it the whole frying thing started to get to me. After i was done i kinda got that same disgusting feeling that i get when i eat fast food. Although they call it a Monte Cristo I wouldnt classify it as such. It's good if you want to have a heart attack
