Mainly because most Americans don't want to eat a (real) asian diet, unlike Mediterranean style food.

What would that diet consist of?

Mostly vegetables, sizable amount of seafood, and rice (if we speak of coastal east asia generically)

That sounds like my Greek diet!

Does the Greek diet consist of flavourless plain white rice?

We eat plenty of rice in Spain, but not white like East Asians do...

		Usually short grain white rice, but it's mixed in food. Things like stuffed peppers and tomatoes or stuffed grape leaves. Not a plain side dish.
