Heat 1½ tablespoons of oil in a large skillet over high heat. Add pork and cook undisturbed for 1 minute. Add a pinch of salt and black pepper then cook for 4 minutes or until brown. Transfer the pork to a colander to remove the excess liquid and fat. Drain and set aside.
Heat 1½ tablespoons of oil in a large skillet over high heat. Add shallots, cook for 1 minute, then add ginger and chili and cook for 1 minute. Add garlic and cook for about 15 seconds. Keep stirring.
Add the browned pork back into the pot and stir. Add fish sauce and brown sugar. Stir then let it cook undisturbed to caramelize for about 1 minute. Stir again for a few seconds and let it cook undisturbed for another 1 minute. Gently scrape up the brown bits from the bottom of the pan to prevent burning. Repeat this process if necessary or until you reach the desired consistency or crispiness. The pork meat should turn golden brown with caramelized flavors. Do not overcook to prevent burnt taste and dry meat. Add salt and pepper if necessary.
Add chopped scallions, lime zest, and lime juice. Give it a quick stir for a few seconds, then turn off the heat. Serve with white rice or lettuce and more lime juice if desired. Enjoy!
