This sandwich is one of the comfort foods in my home. It's so good and dipping in the fruit makes it just over the top. I sometimes don't even dip and I also sometimes top the sandwich with a fried egg. A great breakfast to give you a full belly. This has to be one of my husband's favorite foods.
Heat 5 inches of oil in a deep-fryer to 365 degrees F (180 degrees C). While oil is heating, make the batter: In a medium bowl, whisk together the egg and water. Combine the flour, baking powder, salt and pepper; whisk into the egg mixture until smooth. Set aside in the refrigerator.
Assemble sandwiches by placing one slice of turkey on one slice of bread, a slice of ham on another, then sandwich them with the Swiss cheese in the middle. Cut sandwiches into quarters, and secure with toothpicks.
Dip each sandwich quarter in the batter so that all sides are coated. Deep fry in the hot oil until golden brown on all sides. Remove toothpicks and arrange on a serving tray. Dust with confectioners' sugar just before serving.
Serve with Fried Eggs and a side of Raspberry Preserves.
