For this you really homemade chicken stock. From there it's simple.
Mix 1 tbsp grated fresh ginger, 1 tbsp miso paste and 600 ml chicken stock. Bring to the boil and simmer for 15 mins.

To glaze the chicken:
mix 2 tbsp miso paste with 2 tbsp Mirin and 2 tbsp olive oil. Whisk and use to cover 2 chicken breasts.
Fry the breasts in a bit of oil, 5 mins on each side

Boil some noodles (mine took 3 mins) and an egg for 6 mins.
Add some decorative mushrooms to the broth and cook for 2 mins.

Seve as shown, with some nori, Shichimi Togarashi (a Japanese orange/pepper mix) and some sprouts
