In a large skillet over medium-high heat, add the diced pork belly and cook until the fat renders and the pieces become golden and crispy.
Add the lean ground pork to the skillet, breaking it apart with a spatula, and cook until browned and fully cooked through.
Stir in the minced garlic, grated ginger, and the white parts of the sliced green onions, sautéing for one minute until fragrant.
Add the chopped kimchi and gochujang to the pan, stirring to combine with the meat for two minutes to develop deep flavor.
Incorporate the chilled jasmine rice and coconut aminos, pressing the mixture firmly into the pan and letting it sit undisturbed for three minutes to create a crispy crust.
Create a small well in the center of the rice, pour in the egg and egg whites, and scramble gently until just set before folding into the rice.
Remove from heat, drizzle with toasted sesame oil, and garnish with the remaining green onion tops before serving.
