Halve the cucumer, lengthways and scrape out the seeds with a spoon. Grate the cucumber.
Put the grated cucumber in a mesh strainer over a bowl. Sprinkle some salt on the cucumber and mix it in. Let it sit for a few hours or overnight, if you have time.
Squeeze the cucumber and put it on some kitchen roll to soak up any remaining moisture.
Add all of the ingredients into a large bowl and mix thoroughly. It's best to leave it in the fridge for an hour before eating to let the flavours develop.
Enjoy!
Notes
You can decide how garlicky you want to make it. For me, the more garlic the better!
