Heat a large skillet or wok over medium-high heat.
Add the diced pork belly and cook until the fat renders and the edges become golden and crispy.
Add the lean ground pork to the skillet, breaking it up with a spatula until browned and fully cooked.
Stir in the minced garlic and the white parts of the sliced green onions, sautéing for 1 minute until fragrant.
Add the chopped kimchi and gochujang, stirring to incorporate with the meat for about 2 minutes.
Add the chilled jasmine rice and chopped baby bok choy to the pan, pressing the rice down to let it crisp slightly in the rendered pork fat.
Drizzle with coconut aminos and toasted sesame oil, tossing everything together until the bok choy is tender and the rice is heated through.
Season with sea salt and black pepper to taste.
In a separate small non-stick pan, fry the egg until the whites are set but the yolk remains silky and runny.
Transfer the fried rice to a bowl, top with the fried egg and the remaining green onion tops.
