1 rape, 1 egg, 1 spoon of soy sauce, 10 grams of salt, 3 slices of ham, 1 spoon of sesame oil, 10 grams of pepper. I do is 1 person, if the number of people, appropriate increase the amount, I do not have green onions, you can add some small scallions. Wash the greens, cut the roots, and then a look forward to, two halves, one person food will use 1, 2 people food will use 2. Eggs dashing beaten. Hang a handful of noodles. Bring the water to a boil, throw all these in, add 1 spoon of soy sauce, 1 spoon of salt, 1 spoon of sesame oil, 1 spoon of pepper. When cooked, serve. Cut a few slices of ham to make a show of it, take a picture, and it's ready to eat haha. I think bok choy and egg noodle soup is the easiest, there is no skill, the only thing you need to pay attention to is not to puff the pot. You can add a little sesame oil and pepper to flavor.
