For the Roast Pork: Preheat your oven to 350°F (170°C).
In a small bowl, mix together the minced garlic, dried oregano, ground cumin, salt, pepper, olive oil, orange juice, lime juice, white vinegar, and mojo criollo sauce to create the marinade.
Place the pork in a large zip-top bag or a shallow dish and pour the marinade over it. Make sure the pork is well-coated, and let it marinate for at least 2 hours or overnight in the refrigerator.
Heat a pan or skillet over medium-high heat. Sear the pork on all sides until browned.
Transfer the seared pork to a roasting pan and roast in the preheated oven 20 - 25 minutes until the internal temperature reaches 145°F (63°C).
Set aside to rest for 5 minutes before slicing thin.
Soak the sliced red onion in saltwater in a bowl for about 10 minutes. Then drain and mix with cilantro chili pepper, vinegar, and lime juice.
Place the pork onto the roll, top with the onion mixture.
Mix the ingredients for the lemonade. Serve over ice if desired.
Serve the butifarra with chips, pickle, and lemonade.
Save remaining pork for Wednesday and Friday lunches.
