Start by making the pickling liquor, add all the ingredients to a small pan and warm until the sugar has dissolved.
Peel the carrot and using the peeler or a mandolin, peel it into ribbons. Do the same with the radish and place into two different bowls.
Pour the warm liquid over the carrots and the radish, leave to one side for at least an hour. ( You can do this in large batches as they will keep for a long time refrigerated )
Finely slice the cucumber and season lightly with salt. Now it’s time to build the sandwich, slice open the roll and get the pate and smear the bottom part of the bread, add the sliced chicken breast on top and then add the cucumber, pickled carrot and radish. Add some whole coriander leaves and then drizzle with your favourite chilli sauce, close it up and serve.
