Cut the ends of the green chillies and remove the seeds (this is optional. Keep to the side if you want to add extra heat) and slice and add to a blender or mortar and pestle.
Peel the ginger using the back of a spoon and slice it into small pieces.
Zest the lime and add the zest and juice to the mix.
Dice and chop all other ingredients and add everything to the mix.
Blitz or pound until a paste-like consistency. You may need to add a splash of water if it is not mixing.
Use immediately or freeze for future use.
