I know I'm probably late to the party,
But I've just discovered Greek yogurt (last 6 months) and it has since become a staple in my diet.
I use the plain nonfat 23 grams of protein.
If you're like me and like to experiment in the kitchen, it's pretty versatile. It can be sweet or savory, and is a great substitute for sour cream.
Anyway if you are a fan, I would love to hear how everyone else is using it.
