Also Romanized as chachang-myun and other variations. A Korean dish (at least I've only ever seen it at Korean restaurants) which consists of a big bowl of thick delicious wheat noodles topped with a rich, dark, salty, chunky black bean sauce. The sauce as I've had it has hunks of vegetables in it like onion, squash, carrot and peas and it also usually has hunks of beef or pork in it too. Since I became vegan it has been FOREVER since I've had jajang-myun (the same, alas, can be said for donuts, but that's another matter). It can be made without meat if you're fortunate enough to know someone who knows how to make it though. I think my mom said it was originally a Chinese dish but I've never seen it at Chinese restaurants.
