In a large pot bring the chicken broth, sliced mushrooms, ginger, tamari, chilli flakes and coconut sugar to a simmer and cook for 10 minutes.
In the meantime cook the noodles according to the packet instructions, drain and set aside. Also, boil the eggs for 5 minutes for soft boiled eggs, let cool a little, then peel and slice in half.
Rub the skin side of the salmon with salt. Lay the sesame seeds over a large plate and press the flesh side of the salmon into the seeds. Heat the avocado oil in a large frypan over a medium-high heat and cook the salmon skin side down for 4 minutes, pressing down with a spatula. Turn the salmon and cook for another 2 minutes. Remove the salmon fillets from the pan and slice.
While the salmon is cooking add the edamame (or other green vegetables) to the broth and simmer for 4 minutes.
Ladle 1/2 cup of the broth into a mug or small bowl and stir in the miso paste until dissolved. Stir the miso back into the soup but do not boil as it will destroy the nutritional benefits of the miso. Taste the broth for salt and chilli.
Put some noodles into the bottom of each bowl, ladle over the hot soup, then top with salmon, eggs, shallots, nori and drizzle with sesame oil.
