Well this may be old news but it's new to me - I took two of my containers of Activia yogurt and threw them in the freezer to see how they'd freeze, and upon removing them a day later I am pleasantly surprised. The consistency is harder than icecream but it can still be shaved with a spoon. The yogurt turns into this delicious, healthy treat that took me a few minutes to eat and felt really decadent. It tasted wonderful and felt a bit more like a splurge than a normal container of lowfat yogurt.
If you're struggling with feeling deprived but, like me, can't keep junk in the house this is a great experiment to try. Just thought I'd share
