Looking for a green smoothie recipe

I am looking for a good green smoothie recipe that's not too high in sugar. It's ok if the sugars come naturally from that fruit. I just don't like a lot of added sugars. I had a good one from Panera Bread, but it was pretty high in sugar content. I am looking for one that has kale, kiwi, and other healthy, but delicious foods in it. And maybe one that has some protein power added to it, but that is optional.
