In a small bowl, whisk together the gochujang, tamari, rice vinegar, garlic powder, and ginger powder to create the glaze.
Place the diced pork belly in a cold skillet and turn the heat to medium-high, rendering the fat until the pieces are golden and crispy.
Add the cubed pork tenderloin to the same skillet, searing for 4-5 minutes until cooked through and slightly charred.
Pour the gochujang glaze over the pork and toss for 1 minute until the sauce becomes sticky and coats every piece.
In a separate pan, sauté the cauliflower rice with sesame oil for 3-4 minutes until tender but not mushy.
Wipe the pan and fry the egg to your preference, ideally leaving the yolk slightly runny.
Assemble the bowl by layering the cauliflower rice, the glazed pork, sliced cucumber, and kimchi.
Garnish with sliced green onions and toasted sesame seeds before serving.
