Slice the pork tenderloin and pork belly into small, thin bite-sized strips.
In a small bowl, whisk together the gochujang, coconut aminos, rice vinegar, and toasted sesame oil until smooth.
Heat a large skillet over medium-high heat. Add the pork belly pieces first, cooking until the fat renders and they become golden and crispy.
Add the pork tenderloin strips to the skillet with the pork belly and sear for 3-4 minutes until cooked through and slightly browned.
Stir in the minced garlic and grated fresh ginger, cooking for 30 seconds until fragrant.
Pour the gochujang glaze into the skillet and toss the pork continuously for 1 minute until the sauce thickens and becomes sticky.
Remove the pork from the pan. In the same skillet, add the cauliflower rice and sliced zucchini, sautéing for 3-5 minutes until tender-crisp.
Divide the vegetable base into a bowl, top with the spicy pork mixture, and garnish with sesame seeds and sliced green onions.
