All you really need to know about Korean cooking can be learned from one woman...that is Maangchi. She is my number one go-to regarding Korean foods since she is a) Korean, b) quarky and c) speaks English. Additionally, she not only posts recipes for dishes with lots of pictures, but almost always includes a video, which is just nice...perhaps someday I'll go live on YouTube with my cooking skills! (HA!)
One of my all-time-favorite Korean dishes is Japchae. The dish is made with sweet potato (also called starch or glass noodles), a ton of veggies and a simple sauce of soy sauce and sesame seeds.
There's a ton of veggies in this dish and the meat called for can easily be substituted or simply left out for a more vegetarian friendly option.
I realize the polite thing to do would be to re-iterate the recipe here, but I really, REALLY want you to meet Maangchi, because she's a blast, so here's the japchae recipe and a bit of Maangchi herself!
