In a small bowl, whisk together gochujang paste, coconut aminos, rice vinegar, garlic, and fresh ginger.
Heat toasted sesame oil in a large skillet over medium-high heat.
Season cubed pork loin with sea salt and black pepper.
Add pork to the skillet and sear until browned and cooked through, about 6-8 minutes.
Pour the gochujang sauce over the pork and toss to coat until the sauce thickens and becomes sticky.
In a separate pan, steam the cauliflower rice until tender.
Assemble the bowl by placing the cauliflower rice at the base.
Top with the glazed pork, kimchi, cucumber, and sliced green onions, then garnish with sesame seeds.
