White/light green sauce (possibly thai)?

Question

A Thai woman I know made me a meal once (steak and veg) with a sauce I've never had before. It white white/light green with green herbs in it, but i couldn't really place the flavour. I assume it had garlic and cheese in it because she asked beforehand if I liked those, and they weren't in any other part of the meal. Does anybody know the name/recipe?

Answer 1

I suggest you ask her for the recipe. Authentic Thai food does not use any sort of cheese. It was probably her own invention.  

Answer 2

you might be able to find some recipes on this site - http://www.dummychef.com
