Combine dressing ingredients in a jar and shake well to combine. Set aside for 5 minutes for the flavours to infuse.
Prepare vermicelli noodles per packet directions (usually soak in warm or boiling water 2 minutes). Drain well then set aside for 10 minutes to drain off excess water. Turn out onto tea towel if necessary to dry more (watery noodles = watery flavour).
Combine vermicelli noodles with remaining salad ingredients.
Just prior to serving, toss through dressing. Garnish with Fried Asian Shallots if you wish.
