Love Korean food, and this is one of them. Look for sweet potato noodles in Korean or Asian grocery stores. Or use soba noodles instead. The dish itself is easy to prepare. For the seasonings, you only need soy sauce, sesame oil, rice vinegar, sesame seeds and red pepper flakes that are all easy to find in all the grocery stores. Feel free to use any vegetables you love or you have on hand, such as bok choy, broccoli... A quick and delicious weeknight meal.
