To assemble sandwich, layer one slice of bread, ham, provolone cheese, turkey, and swiss cheese, and then another slice of bread.
Secure all 4 corners of the sandwich with toothpicks.
For the batter, in a bowl beat the egg. Add flour, baking powder, salt, sugar, and water and mix until all smooth.
Dip sandwich in batter, coating all edges and sides.
Carefully fry sandwich until golden brown on each side.
