Dice the pork loin into 1/2-inch cubes and season with sea salt and black pepper.
In a small bowl, whisk together the gochujang, tamari, minced ginger, and minced garlic to create a thick glaze.
Heat the sesame oil in a large skillet over medium-high heat until it begins to shimmer.
Add the pork cubes to the skillet and sear for 5-6 minutes, turning occasionally until golden brown and cooked through.
Pour the gochujang sauce over the pork and toss for 1 minute until the sauce reduces into a glossy, sticky coating.
Remove the pork from the skillet and set aside; add the cauliflower rice to the same pan, sautéing for 3-4 minutes until tender.
Assemble the bowl by layering the sautéed cauliflower rice, the glazed pork, and the kimchi.
Garnish with thinly sliced green onions and toasted sesame seeds before serving hot.
