ema datsi

Ema datsi is the national dish of Bhutan. It's made of melted yak cheese and chilies, kind of like Tex-Mex chile con queso or maybe Welsh rarebit, and it's served over rice.

In the capital, Thimphu, you can also get yak pizza and yak burgers.

I learned this from Cheese and Bhutanese cuisine on Wikipedia, Datsi in the Druk Highlands on mid-day.com, and For Folk Fest, Red-Hot Chilies, Hold the Yak from the Washington Post.  Flickr has some photos of ema datsi.
