Cut the pork tenderloin into 1-inch cubes and set aside.
In a medium bowl, whisk together the gochujang, coconut aminos, toasted sesame oil, rice vinegar, grated ginger, and minced garlic.
Add the pork cubes to the bowl, tossing until every piece is thoroughly coated in the marinade.
Thread the marinated pork onto skewers, leaving a small space between each piece for even cooking.
Heat the avocado oil in a large skillet or grill pan over medium-high heat until shimmering.
Place the skewers in the pan and sear for 3 to 4 minutes per side until beautifully charred and cooked through.
In the same pan, quickly sauté the cauliflower rice for 2 minutes until just tender and infused with the remaining pan juices.
Serve the skewers over the cauliflower rice, topped with kimchi, sliced green onions, and a sprinkle of sesame seeds.
