Place the chicken between two sheets of cling film and bash to flatten with a rolling pin or the flat side of a meat mallet. Season with salt and pepper.
Heat a griddle pan until very hot and cook the chicken over a high heat for 3-4 minutes each side, until cooked through (the juices will run clear when pierced with a skewer or the top of a knife).
Meanwhile prepare the salad and dressing. Place the noodles in a heat-proof bowl and cover with boiling water. stir and allow to stand for 4 minutes or until just tender. Drain and keep warm.
Combine the remaining ingredients for the salad and set aside.
