Wash the cabbage, onion, and baby leaf sprouts thoroughly and cut them into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the onions first.
When the onions become translucent, add the cabbage and stir-fry together.
Season with salt and pepper.
Add the baby leaf sprouts and sauté briefly over low heat.
Place the stir-fried mixture over rice to complete the rice bowl.
