This looks so yummy. Something like 15 years ago a Thai nurse met a Canadian tourist met on an elephant in Northern Thailand. Although she was a nurse she was an absolutely incredible home cook. He wooed to Canada where they started a restaurant business in Toronto specializing in Northern Thai cuisine. Now they have a very successful chain of restaurants that have visited by celebrities and athletes and she has a Bib Gourmand. If you two ever come to Toronto PAI is worth trying.

I believe that vegetable you were asking about was Thai eggplant. It is small and very seedy. I think green tomatoes are only eaten in the U.S., but I could be wrong.
