For the peanut chicken, place the peanuts into a food processor and pulse to crumbs. Tip onto a large plate.
Dust the chicken in the flour, then dip into the beaten egg and finally roll in the peanut crumbs. Heat the oil in a frying pan and fry the goujons, in batches, for 2-3 minutes on both sides, or until golden-brown, crisp and cooked through.
For the pak choi, mix all of the pak choi ingredients together in a bowl. Heat a chargrill pan until smoking, then tip the pak choi mixture in and cook for 4-5 minutes, turning occasionally, or until the pak choi is wilted and tender.
For the dressing, combine all of the dressing ingredients together in a bowl and mix well.
Serve the pak choi alongside the peanut chicken, with the dressing spooned around the edges of the plate.
