Sprinkle salt and ground black pepper all over the pork. Toss the pork to distribute the seasoning. Let it stay for 20 minutes.
Meanwhile, heat the oil in a cooking pot.
Once the oil becomes hot, dredge the pork in cornstarch then deep fry for 5 to 8 minutes or until the color turns golden brown and the texture becomes crisp.
Remove the cooked pork from the cooking pot. Place in a large mixing bowl. Set aside.
Make the orange glaze by combining water, vinegar, and soy sauce in a saucepan. Stir and let boil.
Add the garlic powder and brown sugar. Stir and cook until the liquid reduces in half.
Pour the glaze all over the pork. Toss to coat the pork completely.
Transfer to a serving bowl. Sprinkle the chopped green onions on top.
Serve. Share and enjoy!
