1. Preheat your oven to 300°F (150°C).
2. In a Dutch oven, heat the olive oil over medium-high heat.
3. Add the pork shoulder chunks and sear until browned on all sides.
4. Add the salt, pepper, oregano, cumin, orange juice, chicken broth, onion, garlic, and bay leaves.
5. Bring to a boil, then cover and transfer to the oven.
6. Cook for about 4 hours, until the meat is tender and easily shreds with a fork.
7. Remove the pork from the oven and shred the meat. Discard any large pieces of fat.
8. Optionally, spread the shredded pork on a baking sheet and broil for a few minutes to get crispy edges.
