Slice the pork belly into thin, bite-sized pieces and season with the sea salt and black pepper.
Heat a large cast-iron skillet or wok over medium-high heat and sear the pork belly until the fat has rendered and the edges are golden and crispy.
Mince the garlic, grate the ginger, and slice the scallions, separating the white bottoms from the green tops.
Add the garlic, ginger, and scallion whites to the skillet with the pork, sautéing for 1 minute until highly fragrant.
Stir in the chopped kimchi and cook for 2-3 minutes, allowing the juices to caramelize and the kimchi to soften slightly.
Add the cooked jasmine rice and tamari to the pan, pressing the rice down to ensure it makes contact with the hot surface to develop a slight crust.
Drizzle the sesame oil over the rice and toss everything together until well combined and heated through.
In a separate small non-stick pan, fry the egg to your preference, ideally leaving the yolk runny to create a natural sauce.
Plate the kimchi fried rice, top with the fried egg, and garnish with the reserved green scallion tops.
