Place the olive oil, orange juice, lime juice, garlic, oregano, cumin, salt and pepper in a bowl. Whisk to combine.

Place the pork in the bowl and spoon the marinade over the top. Cover the bowl and refrigerate for at least 1 hour or up to 6 hours.

Step 3

Preheat a grill or skillet to medium high heat. Add the pork and cook for 7-9 minutes per side or until a meat thermometer registers 145 degrees F.

Step 4

Let the pork rest for 5 minutes, then thinly slice the meat.

Step 5

Cut the loaf of bread in half lengthwise. Cut the bread crosswise into 4 equal sized pieces.

Step 6

Place half of the cheese slices on the bottom pieces of bread. Top with layers of ham, pork and pickles.

Step 7

Add the rest of the cheese on top of the pickles. Spread the mustard over the top pieces of bread, then place the tops on each sandwich.

Step 8

Melt the butter in a pan. Place one sandwich in the pan. Use a heavier pan, such as a cast iron skillet to press down on the sandwich. Cook for 3-4 minutes per side or until bread is golden brown and cheese is melted. Repeat the process with the remaining sandwiches.

Step 9

You can also cook your sandwiches in a panini press according to manufacturer instructions.
