Soak wooden skewers in water for 20 minutes to prevent burning during the grilling process.
Slice the pork tenderloin into 1-inch cubes and season them evenly with sea salt and black pepper.
In a small mixing bowl, whisk together the gochujang, coconut aminos, toasted sesame oil, honey, minced garlic, and grated ginger.
Toss the pork cubes in the marinade until thoroughly coated and let them marinate for at least 10 minutes.
Thread the marinated pork onto the prepared skewers, leaving a small amount of space between each piece for even cooking.
Heat a grill pan or cast-iron skillet over medium-high heat and sear the skewers for 3-4 minutes per side until charred and cooked through.
Steam the bok choy until tender-crisp and prepare the cooked brown rice as the base for the dish.
Serve the skewers over the rice and bok choy, then garnish with sesame seeds and thinly sliced green onions.
