Season the pork shoulder evenly on all sides with sea salt, black pepper, dried oregano, and ground cumin.
Place the seasoned pork in a slow cooker, add two cloves of minced garlic and a splash of water, then cover and cook on low for 8 hours until tender.
Once the pork is finished, remove it from the slow cooker and shred the meat into bite-sized pieces using two forks, discarding any excess fat.
In a small bowl, whisk together the olive oil, lime juice, and the remaining two cloves of minced garlic to create the mojo sauce.
Sauté the sliced bell peppers and red onions in a non-stick skillet over medium heat until they are softened and slightly caramelized.
Toss the shredded pork with the prepared garlic mojo sauce until well coated.
Serve the succulent shredded pork alongside the sautéed peppers and onions for a complete, high-protein meal.
