Slice the pork belly into small bite-sized pieces and finely chop the kimchi.
Heat a large skillet or wok over medium-high heat and add the pork belly, cooking until the fat renders and the meat becomes golden and crispy.
Add the minced garlic, grated ginger, and the white parts of the sliced scallions to the skillet, sautéing for 1 minute until fragrant.
Stir in the chopped kimchi and gochujang, cooking for 2-3 minutes to allow the flavors to meld and the kimchi to soften slightly.
Add the cooked brown rice and tamari to the pan, using a spatula to break up any clumps and tossing everything together until the rice is well-coated and heated through.
Push the rice mixture to one side of the pan and crack the eggs into the empty space, frying them until the whites are set but the yolks remain runny.
Divide the fried rice into bowls, top each with a fried egg, and garnish with the sliced scallion greens, sea salt, black pepper, and a drizzle of sesame oil.
