Soak vermicelli noodles in freshly boiled water, per packet directions. Drain then set aside to cool.
Place Dressing ingredients except coriander in a bowl. Whisk well. Stir through coriander. Adjust salt and pepper to taste.
Place avocado and mango in a bowl. Drizzle over 3 teaspoons of Dressing, GENTLY toss.
Place 4 to 5 lettuce leaves on each plate, overlapping slightly (see video for how I do it).
Divide the noodles between each plate. Then spoon over mango avocado salsa, sprinkle each plate all over with red onion and top with prawns.
Drizzle over remaining Dressing all over everything, including the noodles. Serve immediately.
