River moss

Could I suggest some khai paen or river moss as a souvenir?
Moss doesn't sound particularly appetizing. I'm not so vege as to be into lichens and algaes and moulds.
Believe me, it's good. The food's all good here, quite superior to anything they prepare on the Plain of Jars and south.
Hmm. River moss.
It's fried in oil, dried and dusted with sesame seeds. You buy it in green sheets.
Like nori?
Even better than nori. It's in the market. Here. Probably prepared it herself. Highest grade, Ten thosand kip, only a dollar for a big fat pack.
Okay, two.

Sir, sir, how about some water buffalo skin? Or fried grasshoppers?
