Slice the pork belly into thin bite-sized strips and season with sea salt and black pepper.
Place the pork belly in a cold skillet and turn the heat to medium-high, searing until the fat renders and the meat becomes golden and crispy.
Mince the garlic, grate the ginger, and slice the green onions, separating the white and green parts.
Add the garlic, ginger, and the white parts of the green onions to the skillet with the pork, sautéing for 1 minute until fragrant.
Roughly chop the kimchi and add it to the pan along with the gochujang, stirring for 2-3 minutes until the kimchi begins to caramelize.
Add the chilled jasmine rice to the skillet, breaking up any clumps and pressing it down into the pan for 2 minutes to develop a crispy texture.
Push the rice mixture to one side of the pan and pour the egg whites into the empty space, scrambling them until they are just set.
Toss the rice and egg whites together, then drizzle with tamari and toasted sesame oil.
Garnish with the green parts of the sliced onions and serve immediately.
