Heat a pan with oil and stir-fry the chopped kimchi and onion.

Mix the stir-fried kimchi and onion with cooked rice, sesame oil, and black sesame seeds until evenly combined.

Shape the rice mixture into small balls (about 1 tbsp each) and wrap each ball with a strip of bacon.

Cook the bacon-wrapped rice balls in an oven or air fryer at 180°C for 8 minutes, or pan-fry until crispy.
