Spread 1 tablespoon yellow mustard on one side of each slice of bread.
Add two slices of Swiss cheese to 2 pieces of bread.
Top each sandwich with the desired amount of roast pork, 3 slices of ham, and 2 pickles.
Top each sandwich with 2 more slices of Swiss cheese.
Top with bread and thinly coat the outside of each sandwich with butter.
Add to a preheated panini press.
Cook for about 15 minutes until the sandwich is hot and the cheese is melted.
Notes
The best method for this sandwich is the press it low and slow. This ensures the middle of the sandwich will get hot and not burn the outside of the bread. I used my own crispy roast pork for this sandwich.
