It's not too early to start planning what you are going to make with your Thanksgiving leftovers. There might be items you want to pick up and have on hand for the days after the holiday. Goodness knows you won't want to head back to the market (even though it will be empty). Anyway, the Monte Cristo is traditionally a fried ham and cheese sandwich. I have always dined on them at the Blue Bayou, the restaurant that sits inside The Pirate's of the Caribbean at Disneyland. Have you been there? It has been years since I was back but I remember them fondly.
The Monte Cristo is essentially a variation of the French croque-monsieur and my version uses your leftover turkey and cranberry sauce. It's kind of like making French toast but with a sandwich. In other words, it's very easy.
I used Muenster cheese (not to be confused with Munster cheese). Muenster is a great melting variety with a mild, creamy taste. Have the deli counter person slice it as thin as possible.
This sandwich is a great way to use up leftovers, especially if you have to feed a house full of holiday visitors. I think re-purposing leftovers into a completely different meal is always a great way to use them up. No one wants to keep eating the same thing over and over again.
