Found this wonderful Vietnamese recipe in a supermarket leaflet and adapted it to my liking. Everyone I share it with is crazy about it and it has ended up on the lunch menu at the hotel where I work! If you've never used fish sauce before, go for it. It may smell like dirty socks, but it is essential to this dish, do not delete or substitute. If you don't want to bother with all the herbs, just use cilantro, it's still great. Let me know how you like it!
