Drop the noodles in, and then add 1/2 packet of the vegetable flakes. Continue to boil until the noodles are almost cooked, about 3 minutes. The noodles should be al dente at this point.
Crack an egg straight over the noodles. You can break the egg yolk and stir into the soup if you want. Turn the heat off, and drop the scallion in, and sprinkle with pepper to taste.
