Heat a large skillet over medium-high heat and add the diced pork belly, cooking until the fat renders and the pieces become crispy.
Add the diced pork loin to the skillet and season with sea salt and black pepper, sautéing until the meat is browned and cooked through.
Stir in the minced garlic, grated ginger, and the white parts of the sliced scallions, cooking for one minute until the aromatics are fragrant.
Add the chopped kimchi and cooked brown rice to the skillet, breaking up any clumps and stirring to combine thoroughly with the pork and aromatics.
Drizzle the coconut aminos and sesame oil over the mixture, tossing everything together until the rice is heated through and slightly toasted.
In a separate small non-stick pan, fry the egg to your preference, ideally keeping the yolk slightly runny to create a natural sauce.
Transfer the fried rice to a serving bowl, top with the fried egg, and garnish with the remaining green scallion tops before serving.
