I remember when I used to go to McDonalds as a child and all the burgers had gherkins inside. Gherkins seem to have disappeared these days, but if you want to go a bit retro with your burger or sandwich, making your own is very easy. It does require a bit of patience though, as pickling time is required.
If you want to give your gherkins a bit of a kick, just add chillies.
