Boil water for the noodles. They should be wheat noodles, not rice, and neither thick nor very thin.
Cut the meat into thin strips (thinner than you can see in the photo :-D). Season with pepper and salt, and fry in a pan. (But you can also use any other spices that you like. For example, I added a little soy sauce with garlic).
Cut cucumber and tomato into thin strips or quarters in the case of tomatoes.
Break the eggs in a bowl, you can add a pinch of salt and black pepper. Bake in a little oil like crepes and then cut them into thin strips.
Cook noodles according to instructions on the packaging. Wash them under running water to cool them down and to wash off the starch and prevent them from sticking.
Mix all ingredients for dressing.
And let's serve - first put noodles and then gradually each topping, and pour over the sauce. I don't recommend serving in a deep bowl, but rather in a wider plate.
