Bring a small pot of water to a boil, carefully lower the egg into the water, and simmer for 6.5 minutes. Immediately transfer to an ice bath, peel, and set aside.
In a small bowl, whisk together the gochujang, tamari, grated ginger, and minced garlic to create the glaze.
Dice the pork belly into small pieces and the pork shoulder into 1-inch cubes. Season both with sea salt and black pepper.
Place a large skillet over medium-high heat. Add the pork belly and cook until the fat has rendered and the pieces are golden and crispy.
Add the pork shoulder cubes to the skillet with the pork belly. Sear for 5-6 minutes until cooked through and browned on all sides.
Pour the gochujang glaze over the pork and toss for 1 minute until the meat is sticky and well-coated. Remove the meat from the pan and set aside.
In the same skillet, add the toasted sesame oil and cauliflower rice. Sauté for 3-4 minutes until tender and slightly toasted.
Divide the cauliflower rice into a bowl, top with the glazed pork, kimchi, and the soft-boiled egg cut in half.
Garnish with sliced green onions and sesame seeds before serving.
