Spread the toasted bread with 4 tablespoons white sauce and set on a baking tin. Divide the turkey between the 2 pieces of toast. Spread another 4 tablespoons of white sauce on the turkey, and then add the ham. Again spread 4 tablespoons of white sauce on the ham and top with cheese. Bake at 350 degrees for 8-10 minutes or until bubbly. Sprinkle with a dash of paprika and serve immediately. Serves 2.
