I like to actually get the plain Greek yogurt to add stuff into. This way, you're starting with no other flavors, and no added sugar. When I went to Greece, they served this and now it's the only way I eat yogurt!
Slice fresh fruit, Bananas, kiwis, peaches, strawberries, whatever you want and lay them on top of the yogurt and then drizzle honey all over it. It's so delicious, I could cry just thinking about it!!
