I'm with you. I love Activia's granola & yogurt so I know I like yogurt, but Greek yogurt always has me making that 'this is gross!' face. If I stumble across a good one I'll pass it along!
When you first start eating it, you have to get used to it. I think the best way is to add something to it - I like to get the caramel kind from this same brand you have pictured and add a little granola and some fruit - blueberries work well in my opinion. Then you just get kind of addicted and gradually fall in love with all the flavors by themselves.
