Prepare rice, cheese, diced ham, and onion.
Finely chop the onion and ham, then stir-fry them in a pan with oil.
When the onion and ham are cooked, add the rice and stir-fry together.
Once the rice is well mixed, sprinkle cheese on top, cover with a lid, and melt the cheese.
When the cheese is melted, turn off the heat and transfer the finished cheese rice to a bowl.
