I'm Loving No Fat Greek Yogurt

Today I tried no fat Greek yogurt in chicken salad. I made my chicken salad like I normally do except I used 1/2 mayo and 1/2 yogurt. I would not recommend using all yogurt unless you really like the taste of it. It kind of has a sour taste. If any of ya'll have and good substitutions with the no fat Greek yogurt please post them here! You must get some!
