Slice the pork tenderloin into small, bite-sized cubes and season with sea salt and black pepper.
In a small bowl, whisk together the gochujang, tamari, grated fresh ginger, and minced garlic to create the glaze.
Heat the toasted sesame oil in a large skillet over medium-high heat until shimmering.
Add the pork cubes to the skillet in a single layer and sear for 3-4 minutes until a golden-brown crust forms on all sides.
Pour the gochujang glaze over the pork and toss for 1-2 minutes until the sauce thickens and coats the meat evenly.
Remove the pork from the skillet and set aside; in the same pan, add the cauliflower rice and sauté for 3 minutes until tender.
Assemble the bowl by placing the cauliflower rice at the bottom, topped with the spicy pork and a side of kimchi.
Garnish with sliced green onions and sesame seeds before serving hot.
