Fill a pot with water and bring it to boil on a high heat. Wait until the pot comes to a roaring boil.
Then place in a small handful of Dangmyeon noodles. Boil on high heat for 7 minutes.
After 7 minutes, drain the noodles through a strainer and give the noodles a rinse under cold water. Then shake off as much excess water as you can.
Now place the boiled noodles into a mixing bowl. Season it with Soy Sauce (1.5 Tablespoons), Sugar (½ Tablespoon) and Sesame Oil (½ Tablespoon). Stir evenly and give it a taste.
Then add in the stir-fried onions and carrots. Also add in the diced green onion. Toss everything in until it gets mixed evenly.
Now, use a pair of scissors and cut the long noodles and veggies into smaller pieces. (But don't chop too much and turn the noodles small!)
