Fage yogurt
You can also buy it at Fresh & Natural Foods (Shoreview) or most whole foods grocery stores. I think Byerly's and Kowalski's have it, too - just maybe call there first to be sure.
Personally, I use the Fage Total 2% because it has only 4g of fat and more protein (17g) than the 0% (fat free). The 0%/FF has 6g of sugar and the 2% has 8g of sugar, so if that is a concern, then you are wise to go with the 0%. For all the nutrition labels, see their website. http://www.fageusa.com/products.html I use it in lieu of sour cream for the most part. If I want to eat it for yogurt, I simply add some SF vanilla coffee syrup or a tsp. or two of Simply Fruit.
