Cut the pork tenderloin into small 1-inch cubes to mimic the shape of pork belly.
In a small mixing bowl, whisk together the gochujang, tamari, honey, minced garlic, and grated ginger until smooth.
Season the pork cubes evenly with sea salt and black pepper.
Heat the toasted sesame oil in a large non-stick skillet over medium-high heat.
Add the pork to the skillet and sear for 6-8 minutes, turning occasionally, until golden brown and cooked through.
Reduce the heat to low and pour the gochujang glaze over the pork, tossing constantly for 1 minute until the sauce becomes sticky and coats every piece.
In a separate pan, lightly sauté the cauliflower rice for 3-4 minutes until tender but not mushy.
Thinly slice the cucumber and toss with rice vinegar in a small bowl to create a quick pickle.
Divide the cauliflower rice into a bowl and top with the glazed pork, kimchi, and pickled cucumbers.
Garnish the entire bowl with sesame seeds and serve immediately.
