Pad Thai was created for that very purpose, to be an introduction to Thai cuisine in other countries. The history of it is pretty interesting, it's not even a hundred years old
That's because it was made in the 1930's as a form of national identity & been used since 2001 as part of Thailand's Soft Power program: https://en.wikipedia.org/wiki/Pad_thai
