I've been thinking about this question quite a bit. I've yet to find a better answer than Rachel's, but I did do the next best thing, which is find a way to discredit her answer.

In Korea, there's a popular version of bibimbop (rice topped with mixed vegetables and chili sauce) called dolsot bibimbop (stone-pot bibimbop) that's prepared in a piping hot stone pot, which browns the rice and vegetables as you eat. For the past few years in Korea, people have been experimenting with different ingredients to mix in, and one popular variation is prepared by added shredded pizza cheese on top, and usually mixed with something spicy like kimchi. Here are some pictures for evidence.

I don't know if this counts as an answer, as the rice is not in its original state, but browned and mixed with vegetables and sauce. Anyhow, if this does count as "rice", then it certainly can be made better by the addition of cheese. . . Most people who have lived in Korea in the past five or ten years would be able to attest to the awesomeness of cheese dolsot bibimbop.
