This relish can only be made when the fridge Chakra are in perfect alignment.
Firstly you need to find the sacred, almost empty, pickled cucumber jar in the fridge.
Pour some of the pickle juice into a small pan and add some brown sugar, boil it up until syrupy. It will not take long, don't burn it.
Peel and dice ( having removed the seeds and hard bit in the middle) a couple of tomatoes and put in a bowl. Add 4 inches of cucumber diced, some onion diced, the solitary pickled cucumber from the jar diced, salt, pepper, chilli if you like, I use chilli powder but fresh or dried is probably better. Add the syrupy stuff from the pan and stir. you can add a bit of white wine vinegar if you like.
Try it and see what you think. Adjust seasoning but remember things are going to change over the next couple of days.
Now take the empty pickle jar that appeared to be at the end of its useful life and destined for the recycling bin, wash it out and fill with the relish. You will find that you have made exactly the right amount to fill the jar and that the jar lives again.... That is the Zen bit.
Leave it in the fridge for a day or two to macerate.
Great with burgers, kebabs and the like.
