Monte Cristo Sandwiches

¼ cup mayonnaise
2 tsp prepared mustard
8 slices sandwich bread
4 slices cooked turkey
4 slices cooked ham
4 slices Swiss cheese
2 egg whites
3 eggs
½ cup commercial sour cream
2 T milk
About 1 cup fine, dry breadcrumbs
Vegetable oil
Powdered sugar

Combine mayonnaise and mustard, stirring well; spread on one side of each bread slice.  Place one slice each of turkey, ham, and cheese on top of 4 bread slices.  Top with remaining bread.  Cut each sandwich in half diagonally; secure with wooden picks.

Beat egg whites until stiff; set aside.  Beat eggs; add sour cream and milk, stirring well.  Fold in egg whites.  Dip sandwich halves in batter; coat with breadcrumbs.  Carefully lower sandwich halves, one at a time, into deep hot oil (375°); fry until golden brown, turning once.  Drain; remove wooden picks.   May sprinkle with powdered sugar.  Serve sandwiches immediately.  Yield:  4 servings.
