Whilst the sauce is cooking, chop the veg into strips or chunks and add some boiling water into a wok or large deep pan. No need to cook these in oil. Sprinkle with a little salt to bring out the flavours. stir fry for up to 5 minutes.
Blitz the sauce with a hand blender until a smooth consistency. Add this to a fry pan and place the browned chicken into this mix. Cook the chicken for 18+ minutes, until cooked through.
