Monte Cristos are retro in all the best ways. You start with a ham and cheese sandwich that has a generous coating of Dijon mustard, and then dip it in a French Toast-style batter of eggs and milk. Once the sandwich is fried in salted butter (yes, that’s right) you dust with powdered sugar and serve dipped in jam. It sounds crazy, but it’s totally delicious. Make this for a decadent breakfast or cut into bite-sized pieces for a cocktail party hors d’oeuvre.
