Preheat a stovetop grill or sandwich press.
Slice the sub rolls end to end. Spread the butter evenly on both rolls. Repeat the process with mustard. Lay the ham, cheese, and pickle slices evenly in the roll. Put the sandwiches in a press or on the grill and cook for about 6 minutes, or until warm through or toasted on the outside.
