Cut the cabbage, chicken breast, kimchi, and onion into bite-sized pieces.
Add olive oil to a pan and stir-fry the chicken breast.
When the chicken breast is cooked, add the onion and cabbage and stir-fry together.
Once the vegetables are softened, add the kimchi and continue to stir-fry.
Add the rice and mix well while stir-frying.
Taste and season with salt or pepper if needed.
