This is worth making it is so delicious! Greek yogurt is richer and thicker then regular yogurt and is the best used for this recipe, if you cannot find Greek yogurt just use 4 cups regular full-fat plain yogurt and drain it in the fridge through a triple thickness of cheesecloth for 8 hours or overnight, if you are using Greek yogurt you will not have to strain it, once you try Greek yogurt you will never go back to regular yogurt again! Plan ahead this needs to chill for a minimum of 2 hours, you won't be able to keep your spoon out of the bowl LOL! Make certain to drain the cucumber very well for this. Serve this anyway or with anything you want to, it is great on pita. Prep time is only if you are using the Greek yogurt if you are straining the yogurt prep time will be more.
