This is a Chinese recipe that's fun and easy to make, if you've got everything ready. It's best if it's wok tossed, but if you don't have a wok handy, then a normal (large is best!) frying pan and some good ol' shoving around will do the trick!
When doing the actual cooking, you may have to cook the chicken in batches (step 2 doesnt require you putting them in batches, but if you don't have a big enough bowl, then this is best). If so, just change the ingredient amount for each batch accordingly, i.e. if you are doing 2 batches, put in 1/4 cup fish sauce instead of 1/2 etc
You may replace light soy sauce with dark soy sauce.
