Step 1

Bring several quarts of water to boil in a large pan or dutch oven. Add the noodles and cook for 3 or 4 minutes until the noodles are about halfway cooked. Drain and hold the noodles in a bowl while the rest of the meal is prepared. It's okay if there's some cooking liquid with the drained noodles. You can use it to help keep things from sticking if necessary.

Step 2

Make the sauce by whisking the ingredients together in a bowl.

Step 3

Rinse and dry the pan, then return to high heat. Add a tablespoon of vegetable oil and a pinch of red pepper flakes.

Step 4

Stir fry the mushrooms and green onions for a couple minutes. Then use tongs to transfer the noodles to the pan and gently mix together. Add more oil or some of the reserved cooking water to prevent everything from sticking.

Step 5

Pour the sauce evenly over the noodles and mix to distribute throughout and warm everything through. Again, add more water, oil or soy sauce to help keep things from sticking.

Step 6

Transfer to a bowl and garnish with sesame seeds and the remaining tops from the green onions.
