Lightly oil your frying pan with the sesame oil. Add the ginger and garlic and fry gently.

Add one of the oyster mushrooms sliced into thin slices. Let them fry for 5 minutes. Add the soy sauce and continue to fry for a few minutes.

Now add the second oyster mushroom diced into smaller cubes. Add the red chilli, fish sauce, the white half of the spring onion, the sugar and a dash of water.

Let the mushrooms continue cooking while your soba noodles cook.

Then drain the noodles and add to your pan. Mix it all together and serve topped with the remaining spring onions and sesame seeds.
