Step 1

Combine orange juice, Sazon Goya, cilantro, olive oil, lime juice, and garlic in a blender or food processor and blend until garlic is minced and cilantro is finely chopped.

Step 2

Place pork into a resealable bag or large bowl and cover with blended sauce. Marinate for 30 minutes or overnight.

Step 3

When you're almost ready to cook the pork, preheat the oven to 425 degrees F.

Step 4

Place pork in a roasting pan or casserole dish and reserve the marinade.

Step 5

Roast pork for 30 minutes, then turn the oven to 375 and roast for 90 minutes or until desired tenderness.

Step 6

Remove pork from the oven and reserve the drippings.

Step 7

Whisk together 1/4 reserved drippings with 1/2 cup reserved marinade in a small saucepan over medium heat until combined.

Step 8

Remove dripping mix from heat and pour over roast pork.

Step 9

Carve the pork into thin slices.

Step 10

Slice the bread into long rectangles and cut each rectangle in half.

Step 11

Combine mustard and mayonnaise.

Step 12

Spread the mustard mixture on each half-rectangle of bread, then layer with 2 slices of Swiss cheese, 2 slices of ham, 3 to 4 thin slices of roast pork, and 2 pickle slices.

Step 13

Top the sandwich with two more slices of Swiss cheese before finishing off with the other half of the bread.

Step 14

Press the sandwich down gently to compress, then flatten it even further using a panini press or cast-iron skillet.

Step 15

Heat the sandwich in the panini press or another skillet as you continue to press down on it. Cook until the cheese is melted and the bread is flattened.

Step 16

Remove sandwich from press or pan and slice in half diagonally before serving.
