Grate the cucumber with the coarse side of a grater. Don’t peel the cucumber; the skin adds color and texture to the sauce.
Put cucumber in a strainer and sprinkle salt on top. Mix well and let the liquid drain for 10 minutes.
Wrap cucumber in a tea towel and squeeze out excess liquid.
Mix together all the ingredients and let the sauce sit in the fridge for at least 15 minutes before you eat.
Fry the saganaki on medium heat for a few minutes on each side, or until golden.
