Slice the cucumber in half lengthways. Use a teaspoon to scrape the seeds from the middle of the cucumber. This is where most of the water content is in the cucumber. It is up to you whether you peel the cucumber or not - sometimes I do, sometimes I don't!

Grate the cucumber using a coarse grater. 

Place the grated cucumber in a clean tea towel and gently squeeze out as much of the moisture as you can. 

Place the grated cucumber in a bowl with the minced garlic, chopped mint (if using), the juice from ½ a lemon and the salt. Mix together before stirring in a tub of fat free Greek yogurt. 

Serve as an accompaniment to grilled fish and meat or as a dip.
