Cut the pork tenderloin into even 1-inch cubes and place them in a glass mixing bowl.
In a small jar, whisk together the gochujang, tamari, toasted sesame oil, honey, grated ginger, and minced garlic until smooth.
Pour the marinade over the pork cubes, tossing well to ensure every piece is coated, then let sit for at least 15 minutes.
Thread the marinated pork onto skewers, ensuring they are not packed too tightly to allow for even cooking.
Heat a cast-iron grill pan over medium-high heat and sear the skewers for 3 to 4 minutes per side until the edges are beautifully charred.
In a separate skillet, sauté the cauliflower rice with sea salt and black pepper for 5 minutes until tender and lightly golden.
Arrange the skewers over the cauliflower rice and garnish with a sprinkle of sesame seeds and fresh green onions.
