Monte Cristo

Preheat oven to 275 degrees F. Set a wire rack on a baking sheet and lightly coat with cooking spray. Place the baking sheet in the oven.

Whisk egg, egg whites, milk and nutmeg in a shallow dish until combined.

Spread 1 teaspoon jam on each slice of bread. Divide turkey, ham and cheese evenly among 4 slices. Top each sandwich with another slice of bread, jam-side down.

Coat a large nonstick skillet with cooking spray and heat over medium-low heat. Dip 2 sandwiches into the egg mixture, making sure to coat both sides. Place the battered sandwiches in the pan, cover and cook until browned and the cheese is melted, 3 to 5 minutes per side. Transfer to the oven to keep warm. Repeat with the remaining 2 sandwiches. Serve warm.
