02Add the sliced mushroom caps, the salmon fillets, the spinach and the white and light green parts of the scallions to the simmering stock. Cover and turn off the heat. Allow to sit for 5 minutes without removing the cover. The salmon should be just cooked through. Leave it a little longer if you want it more opaque.
03Place a piece of salmon on top of the noodles in each bowl. Ladle in the soup, taking care to distribute the spinach, mushrooms and scallions evenly. Sprinkle on the dark green parts of the scallions, garnish with cilantro and serve.
