Step 1

In a bowl, whisk together the orange juice, lime juice, olive oil, garlic, oregano, cumin, salt, and black pepper to create the marinade. Optional: Coat the pieces of pork in the marinade and refrigerate for a few hours or overnight to infuse with more flavour, otherwise go straight to cooking.

Step 2

Add ¼ cup of water or chicken stock to the bottom of the Instant Pot.

Step 3

Place the pork chunks in the Instant Pot and pour the marinade over the top, ensuring that all pieces are coated with the marinade.

Step 4

Close the Instant Pot lid and set the valve to the sealing position.Select the "Manual" or "Pressure Cook" button and set the timer for 60 minutes on high pressure. After the cooking cycle is complete, allow the Instant Pot to release pressure naturally for 10-15 minutes, then manually release the remaining pressure.

Step 5

Remove the pork from the Instant Pot and shred it using two forks.

Step 6

Using the Saute function, cook down/reduce the cooking mojo liquid for 5-7 minutes, stirring a few times. Then pour over the pork when serving so it absorbs all those delicious juices.

Step 7

Optional broiling: Transfer the pork and juices to a baking dish and pop under the Broil/Grill in the oven for 5-10 minutes to crisp up and get a few brown edges.

Step 8

While the pork is cooking, prepare the ingredients for sandwiches OR side dishes such as rice or tortillas.

Step 9

Using a knife, halve the rolls. Begin building the sandwiches. First, spread a thin layer of Dijon mustard onto one side of the bread and mayo on the other. Add 5 pickle slices, about 3 ounces (90 g) of ham and a few slices of roasted pork. Top with 2 slices of the cheese. Repeat with the remaining sandwiches.

Step 10

Heat a flat-top griddle pan or skillet (you can also do this on a BBQ) to medium heat and add a little olive oil. Place the sandwiches on to the griddle pan and place a weighted cast-iron pan on top to press or even just a lid to trap the heat in. Press the sandwiches until the bread is toasted and the cheese is melted, 2 to 3 minutes. Remove and cut in half. Secure with bamboo skewers if needed and serve immediately.
