What can I do with lots of plain sweetened yogurt? I have a several gallons of yogurt intended for smoothies.  So far I have been eating it over fruit and in various types of shakes.  I've also made some frozen yogurt.  

What else I can make, be it sweet or savory?
I like to spice up Yogurt with Garlic. For 200ml of Yogurt, take about two tea-spoons of olive oil, one crushed garlic clove, a pinch of salt, pepper to taste. Let it steep for at least an hour. Then use it to dip in slices of Baguette or grilled meat.
