Drain and rinse the jackfruit. Chop off the center core portion of the fruit and discard (see photos in post above).
Heat the oil over medium-high heat in a large skillet, then add the onion and garlic and cook until soft, stirring occasionally.
Add the jackfruit, and soy sauce and cook until golden brown, stirring occasionally.
Add the spices (salt, black pepper, chili powder, cumin, and oregano), and stir. Cook for 2-3 more minutes, stirring occasionally.
Add the vegetable broth and orange juice, and simmer covered for 15-20 minutes, stirring occasionally. Add extra vegetable broth or water if necessary.
Remove the lid, and use two forks to shred the jackfruit directly in the pan.
Then cook over high heat for 3-5 minutes, stirring frequently.
Serve immediately or store leftovers in and airtight container in the refrigerator for up to 1 week or in the freezer for up to 3 months.
