Prepare the glaze by whisking together the gochujang, tamari, toasted sesame oil, rice vinegar, honey, minced garlic, and grated ginger in a small bowl.
Slice the pork loin and pork belly into thin, bite-sized strips about 1/4 inch thick.
Heat a large skillet over medium-high heat and add the pork belly strips first, rendering the fat until they begin to crisp and turn golden.
Add the pork loin strips to the same skillet and sear until fully cooked and browned on the edges, approximately 4-5 minutes.
Pour the gochujang glaze over the pork and toss continuously for 1 minute until the sauce becomes sticky and coats the meat evenly.
In a separate small pan, lightly sauté the cauliflower rice for 3-4 minutes until tender, then divide into serving bowls.
Wipe out the small pan and fry the egg over medium heat until the whites are set but the yolk is still runny.
Assemble the bowls by topping the cauliflower rice with the glazed pork, kimchi, sliced cucumber, and the fried egg.
Finish the dish by garnishing with sesame seeds and thinly sliced green onions.
