Slice bread horizontally in half. Spread a thin layer of mustard on the top and bottom half of the bread. Evenly distribute the ham, pork, pickles and swiss cheese on the bread. Cover the sandwich with the other half of the bread and cut into four sandwiches.
Press each sandwich in a hot, buttered sandwich press until bread has browned and the cheese is melted. Remove the sandwich from the press, cut in half and serve.
