Step 1

Make a paste by squishing garlic, salt, and peppercorns together. Mix in the orange juice, onion, and oregano. Let it sit for 30 minutes.

Step 2

Heat olive oil in a pot until it's warm. Take it off the heat and carefully mix in the garlic-orange juice mix. Let it cool before using it to marinate the pork.

Step 3

Poke holes all over the pork with a fork or knife. Put it in a pan and pour the garlic mixture over it (save some for later). Cover and put it in the fridge for 2-3 hours.

Step 4

Preheat the oven to 375°F. Take the lid off the pork and roast it for 20 minutes. Then, turn the heat down to 225°F and roast it for about 2 hours and 20 minutes until it's tender. Baste it now and then. Let it sit for 10 minutes before slicing.

Step 5

Spread butter and mustard on the inside of the bread. Put pickles, pork, ham, and cheese on the bread. Don't be shy with the fillings!

Step 6

Butter a hot pan or griddle. Put the sandwich on it and press it down with a heavy skillet or something flat. Cook for about 3 minutes on each side until it's golden brown and the cheese is melted.

Step 7

Cut the sandwich diagonally and serve it up hot!
