This is not a Greek recipe. This is what greeks call "Tzatziki", a word derived from "Cacik" which is Turkish rooted word. As always greeks, represent Turkish food as if they are greek. "Yogurt" is also turkish very few know that yogurt was introduced to world by Turks. Yog is the root of the word which means condense and is related to yogun "intense," yogush "liquify" (of water vapor), yogur "knead."
This so called greek yogurt sauce is totally turkish and all the etmyological evidence is out there and should be respected as it is especially by cooks.com which is pioneer in the field of food recipes.

Reminds me of Greece! Very nice!
