requires an asian grocery nearby that offers fresh egg noodles. This recipe is significantly worse with dried or wheat noodles.
bok choy, chinese broccoli, or their relatives are my go-to choice. basically anything green with leaves and some stalk will work well.
for the most authentic dish, consider getting some cha siu, beef brisket stew, or roast duck from your local Cantonese deli. But really any protein works.
