I should have had some onions...
Cut the sliced pork belly, kimchi, napa cabbage, and enoki mushrooms into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the sliced pork belly on both sides.
Add the kimchi and napa cabbage, stir-fry together, then add the enoki mushrooms.
Add gochujang (Korean red pepper paste), soy sauce, sugar, and minced garlic, and stir-fry until the seasoning is well absorbed.
Serve the stir-fried mixture over a bowl of rice to finish.
