Place pork tenderloin in a zipper top bag with 1 cup mustard. Marinate at least 2 hours or best overnight.
Fit George Foreman® Rapid Grill Series with ceramic grill plates and preheat to 400 degrees. Take pork out of marinade and dab off excess mustard sauce with a paper towel. Season with salt and pepper and place on hot grill. Grill for about 5 minutes a side, until caramelized on all sides and interior temperature is at 145 degrees. Set aside to rest. Slice tenderloin thin with a sharp knife and set aside for sandwich build.
Sandwich Build & Cook
Preheat George Foreman® Rapid Grill to 350 degrees. Brush one side of each slice of bread with olive oil. Layer on bottom slice, 1 slice of swiss, then about 4-5 thin slices of the tenderloin, then about 6 slices of ham, ribboned high, then 3 slices of crispy bacon. Top with slaw, dash of dressing, and one more piece of cheese. Place last slice of olive-oiled bread on top and place on grill until golden brown and cheese is melted.
Cut on the bias and serve!
For Crispy Bacon

Remove bacon and let drain. Set aside pan and let cool, once cool, carefully toss the parchment with the solidified fat directly in the garbage or reserve fat for future use.
