1Heat 2 tablespoons oil in a nonstick skillet over medium heat. Add shredded pork, chopped onion, orange juice concentrate, cumin, chili powder, garlic powder, cayenne pepper, salt, and pepper. Bring to a boil, cover, reduce heat to low, and simmer until onion is tender, about 20 minutes.
2Remove lid, increase heat to medium, and continue to cook until the liquid is mostly evaporated, about 10 minutes. Transfer everything to a plate and allow to cool slightly. Wipe the skillet clean with paper towels.
