Hi all! I just made this with some olive oil added, as well. It's delicious.

Also, I like a nice thick tzatziki for dipping, so I strained the whey out of the yogurt first. To do this, you just have to spoon the yogurt over a coffee filter and a strainer, and put that over a bowl. Let it sit in the fridge all day while you're at work. Come back and you've got yogurt "cheese." You just have to make sure there's no gelatin added to the yogurt.

Tasty!
