If you like French toast and grilled cheese, you'll love a Monte Cristo. This sandwich is usually pan-fried, but baking it instead means you can use less butter and make several at the same time.
Preheat oven to 400 degrees. Line a baking sheet with a nonstick baking mat; brush with butter. In a 9-by-13-inch baking dish, whisk together eggs and milk. Season with salt and pepper.
Spread cranberry sauce on 4 slices of bread. Top with turkey; season with salt and pepper. Sprinkle cheese evenly over turkey. Top with remaining bread slices. Carefully transfer sandwiches to egg mixture and soak, pressing lightly with a spatula, 1 minute a side.
Transfer to baking sheet; bake 15 minutes. Flip and bake 7 minutes more. Let rest 5 minutes before serving.
It's best to start with an excellent-quality whole loaf of Pullman bread, so you can cut it into the thick slices that make this sandwich so good.
