Pour the broth into a pot, add some soy sauce and heat until boiling.
Boil the egg beforehand — quail egg for exactly one minute, or a regular egg for five minutes if you want a little gooeyness inside — cool and peel.
Put the noodles into the boiling broth so they absorb some of its goodness.
At the same time julienne the carrot and chop some green onion or chives.
Put everything nicely into a bowl — noodles and broth, the sliced grilled chicken thigh, carrot, egg and green onion, topped with seaweed chips if you like — and enjoy!
