Cube the pork tenderloin into bite-sized pieces and finely dice the pork belly.
In a small bowl, whisk together the gochujang, coconut aminos, rice vinegar, minced ginger, and garlic.
Place a large skillet over medium-high heat and add the pork belly, cooking until the fat renders and the bits are golden and crispy.
Add the pork tenderloin cubes to the skillet and sear for 4 to 5 minutes until browned on all sides and cooked through.
Pour the gochujang sauce mixture over the pork, tossing quickly to coat every piece in the sticky, spicy glaze.
In a separate pan, sauté the cauliflower rice with sesame oil and sea salt until tender and fragrant.
Divide the cauliflower rice into bowls and top with the glazed pork, fresh cucumber slices, and kimchi.
Garnish with sliced green onions and sesame seeds before serving.
