Athenos (the fine feta people) just came out with a Greek yogurt duo thing -- strained Greek nonfat yogurt with either honey or blueberries to mix in.
I'm a total Greek yogurt skeptic because I've hated every brand I've tried, but Safeway sucked me in with its $.69 introductory price.
And man, it's good. I've been eating the honey combo, because I'm violently allergic to blueberries, and I'm a big fan. I did a quick google search and there are tons of coupons out there if you want to try it. Curious to see what you guys think.
