@gaiatenshi — what kind of joke is Pepsi?
bring three cups of water to a boil in a small saucepan. add the noodles and cook for two minutes. add the flavor packet, stir, and continue to cook for another thirty seconds. remove the pan from the heat and carefully add the egg. do not stir, pull the noodles over the egg and let sit for one minute to poach. carefully transfer everything to a serving bowl, add the butter, cheese and sesame seeds and mix. garnish with the scallions if desired.
