Dice the pork tenderloin into small, half-inch cubes and season evenly with sea salt and black pepper.
Heat a large non-stick skillet over medium-high heat and add the sesame oil.
Sear the pork cubes in the hot oil until they are golden brown and crispy on all sides, then remove them from the pan and set aside.
In the same skillet, add the minced garlic and chopped kimchi, sautéing for about 2 minutes until the mixture is fragrant and slightly softened.
Add the cooked jasmine rice and gochujang to the skillet, using a spatula to press the rice down firmly into the pan to develop a crispy crust.
Stir in the tamari and return the cooked pork to the pan, tossing all ingredients together until well combined and heated through.
In a separate small non-stick pan, fry the egg to your preference, keeping the yolk runny for extra richness.
Transfer the fried rice to a bowl and top with the fried egg and thinly sliced green onions before serving.
