How to Make Mojo sauce:

• Take the garlic, salt pepper and oregano and crush them to a paste using a mortar and pestle (or a food processor).

  Pour some of the sour orange juice little by little to loosen the paste. A good substitute for sour orange juice is a mix of orange juice (2 parts) and 1 part lemon juice and one part lime juice.
• If working with a mortar and pestle, you'll need to work in batches, so scoop out the paste and continue with the rest of the garlic cloves and spices until finished.
• Once all the ingredients have been mixed, let it sit at room temperature for at least 30 minutes.

How to Make the Sandwich:

• Coat a frying pan in some cooking oil and place over medium heat. Get your pork meat slices and place them in the pan. Leave them for a couple of minutes on each side, or if you like them crispier, fry for longer according to your taste.
• Slice the bread loaves in half and butter each side. Shred the pork pieces and add the meat in an even layer on the bottom half of the bread. Layer a generous amount of thinly sliced onion on top and add a few dollops of delicious mojo sauce.
• Slice the sandwich in half diagonally and serve. If you'd like it ward, finish the sandwich using a sandwich press, though typically this sandwich is served at room temperature and is not pressed.

Enjoy!
