Slice the pork loin into very thin strips and finely dice the pork belly.
In a small bowl, whisk together the gochujang, tamari, honey, grated ginger, and minced garlic to create the glaze.
Heat a large skillet over medium-high heat and add the pork belly, cooking until the fat renders and the pieces are golden and crispy.
Add the pork loin strips to the skillet and sear for 2-3 minutes until browned and cooked through.
Pour the gochujang glaze into the pan, tossing the pork constantly for 1 minute until the sauce thickens and caramelizes onto the meat.
Remove the pork from the pan and set aside; add the sesame oil, cauliflower rice, and chopped bok choy to the same skillet.
Sauté the vegetables for 3 minutes until the bok choy is tender-crisp and the cauliflower rice is heated through.
Assemble the bowl by layering the cauliflower rice and bok choy, topping with the glazed pork, kimchi, sliced green onions, and sesame seeds.
