Another take on bok choy

Spicy rice noodles with
bok choy & salmon

So I didn't post about this recipe before I left for 9 weeks in Russia, so the details are a little fuzzy.  I know that I used salmon instead of steak, and that the results were AMAZING.  As usual, the fish sauce adds a lovely depth to the dish.  One day, I'd love to know when to add it without having it called for in a recipe.  But for now, I'm happy to use it whenever I see it listed in the ingredients!
