Last night I made tuna salad with greek yogurt and put in some horseradish mustard for a kick. It turned out really good and tasted better than putting greasy mayo in there.

_{Sounds yummy! I like greek yogurt with crumbled blue cheese...may sound weird but I love it.}

I had recently posted a recipe for chicken salad, with greek yogurt and it is really delicious - I agree, it is a good substitute!
