Place vermicelli in a microwave-safe container, add enough water to cover, and microwave at 600W for 7 minutes. Rinse with cold water, drain, and cut into manageable lengths.

Slice the red onion thinly. Cut cilantro into 4cm pieces, reserving 1/5 for garnish.

Heat salad oil in a pan over medium heat, add chicken mince, and stir-fry until crumbly. Add seasoning ingredients and simmer until liquid evaporates.

Mix sauce ingredients in a bowl, add vermicelli, and toss. Add cooked chicken mince, red onion, and 4/5 of the cilantro, mixing gently.
