The way we made monte cristos at the restaurant:
make a mixture out of VERY well-squeezed crushed pineapple, sour cream, and honey.
Spread a bit of this on white bread, ham slices and swiss cheese slices, more pineapple mixture. Dip sandwich in a well-beaten egg and deep fry. When it comes out lighlty dust it with powdered sugar and serve with more pineapple mixture. It's the deep frying that would be difficult unless you had one that got up to the right temperature. Place it in the oil with a pair of tongs and hold it for a couple seconds then let go.
