Cut up the pork tenderloin into small bite-sized pieces and season with salt and pepper; set aside.
Heat oil in a large skillet set over medium-high heat.
Add diced onions to the heated oil and cook for 2 minutes. Stir in garlic and cook for 15 seconds, or just until fragrant.
Add pork to the skillet; season with brown sugar, oregano, chili powder, and cumin. Cook, stirring frequently, for about 10 minutes, or until pork is cooked through.
Stir in orange juice; continue to stir and scrape up the browned bits from the bottom of the pan. Add lime juice and continue to cook for 2 more minutes.
Remove from heat. Taste for salt and pepper and adjust accordingly.
Serve in tacos, burritos, over rice, and/or on salads.
