Slice the pork loin and pork belly into very thin, bite-sized strips.
In a small bowl, whisk together the gochujang, tamari, rice vinegar, toasted sesame oil, grated ginger, and minced garlic.
Heat a large skillet over medium-high heat and add the pork belly first, rendering the fat until it begins to crisp.
Add the pork loin to the skillet and sear until browned and cooked through.
Pour the gochujang sauce mixture over the meat and toss for 1 minute until the sauce is thick and glossy.
In a separate pan or microwave, steam the cauliflower rice and warm the cooked brown rice, then mix them together to create a high-volume base.
Place the fresh baby spinach in the bottom of a bowl, top with the rice mixture, the glazed pork, and the tangy kimchi.
Garnish with sliced green onions and sesame seeds before serving for a dangerous kick of flavor.
