Ready, Set, Cook! Hidden Valley Contest Entry. I absolutely love Greek chicken salads, as well as traditional tzatziki sauce typically found on gyros, so I combined the two dishes to create this delicious pizza. The Hidden Valley® Original Ranch® Harvest Dill Dips Mix is a perfect accompaniment to all the simple, delicious ingredients. In each bite, you get the creamy, garlicky tzatziki as well as the savory chicken, salty olives, rich tomatoes, and tangy feta. Greek perfection!
