Cut your thin pork slices into bite-sized pieces. Then add-in Sugar (4 Tablespoons) and mix it evenly into the meat. Place the meat aside for 10 minutes to tenderize.
In the meanwhile, cut 1 whole onion into thin slices. Then cut the stalks of spring onion into thin slices as well.
After 10 minutes, add the onion and spring onion pieces into your mixing bowl with the meat. Now, add in Fish Sauce (4 Tablespoons), Minced Garlic (2 Tablespoons), Grated Ginger (1 teaspoon!). Thoroughly mix everything together with your hands.
After the initial mix, finish with some Sesame Oil (2 Tablespoons) and Black Pepper (few shakes). Give it one final mix. Let it marinate for at least 30 minutes. (If you have some time, let it sit for 1-2 hours, the longer the better!)
After letting it sit in the marinade, place a frying pan on medium-high heat. Place a drizzle of oil in. Then place each piece in and let it cook until you start to see browning on the meat pieces. From then on, move the pieces around frequently so that they don't burn and continue cooking until you get nice crisp edges on the meat.
Garnish with sesame seeds (optional)
Serve alongside a variety of lettuce and greens. Throw in some thinnly sliced cuts of garlic and chili peppers.
