Flatten the chicken breast between clingfilm using a rolling pin until it's around 1cm thick.
In a bowl, add half the Colman's Salt and Pepper Chicken sachet. In another bowl, mix the rest of the sachet with the breadcrumbs. In a third bowl, mix the egg.
Coat the chicken in the seasoning, then the egg, then the seasoning-breadcrumb mix.
Pan fry until golden on each side, then cook on 180’ in the oven for 12-15 minutes.
Meanwhile make the Asian style slaw, finely slicing the onion, carrot and pak choi.
Mix with the rice vinegar, soy sauce and mayonnaise, then add freshly chopped coriander.
Toast the buns, add spicy Mayo (optional) with the chicken and the slaw. Enjoy!
