Whisk the gochujang, tamari, rice vinegar, grated ginger, and minced garlic together in a small bowl until smooth.
Heat the sesame oil in a large skillet over medium-high heat and sear the cubed pork tenderloin until golden brown and cooked through.
Pour the gochujang sauce over the pork and toss for 1-2 minutes until the glaze is thick, glossy, and perfectly coats the meat.
In a separate pan, sauté the cauliflower rice for 3-5 minutes until tender and slightly toasted.
Soft-boil the egg by simmering in boiling water for 6.5 minutes, then immediately transfer to an ice bath before peeling and slicing.
Assemble the bowl by layering the cauliflower rice at the base, followed by the glazed pork, tangy kimchi, and the soft-boiled egg.
Garnish the bowl with sesame seeds and thinly sliced green onions before serving warm.
