One of my family's all-time favorites, we really love this simple old-time version of the Monte Cristo Sandwich! It's great for breakfast, brunch, lunch or dinner. Traditionally dusted with confectioner's sugar, and served with red currant jelly for dipping. You can add a dab of Dijon mustard, if desired. Although this sandwich can be quartered and deep-fried, many of the earliest recipes, like this one adapted from 'The Brown Derby Cookbook' (Doubleday, 1949), call for frying it in a skillet, like french toast.
