Bring a large saucepan of water to the boil. Add the noodles and cook for 5-6
minutes or until cooked. Drain and run under cold water. Drain well. Place in a large bowl with half the sesame dressing and toss gently to coat.
Place both sesame seeds on a small plate and mix together. Press one side of each wedge of avocado into the sesame.
Divide the noodles, cabbage and zucchini between bowls. Top with avocado, trout, cucumber and ginger. Drizzle with remaining dressing and scatter with the nori.
You can use a julienne vegetable peeler, available at Asian supermarkets, or alternatively simply cut the zucchini into matchsticks using a sharp knife
Available in the Asian aisle at most supermarkets and also at Asian supermarkets
