Dice the pork tenderloin and pork belly into small, uniform half-inch pieces.
Place a large skillet or wok over medium-high heat. Add the pork belly first, cooking until the fat renders and the meat becomes golden and crisp.
Add the pork tenderloin to the skillet, seasoning with sea salt and black pepper, and sauté until cooked through and slightly browned.
Stir in the minced garlic, grated ginger, and the white parts of the sliced green onions, cooking for 60 seconds until highly fragrant.
Add the chopped kimchi and gochujang to the pan, stirring constantly for 2 minutes to allow the flavors to meld and the kimchi to caramelize.
Incorporate the cooked jasmine rice and tamari, breaking up any clumps and tossing everything together until the rice is evenly stained red and heated through.
In a separate small non-stick skillet, heat the toasted sesame oil over medium heat and fry the egg until the edges are crispy and the yolk is still runny.
Transfer the fried rice to a bowl, top with the fried egg, and garnish with the remaining green onion tops.
