Yogurt with Blueberries & Honey

As regards the one-star review: my standard Oikos plan Greek yogurt has 18g of protein in a 3/4 cup serving. Increase that to a full cup and you’ve almost hit the 23 shown in the calculation.

I really like this recipe, though I use a bit more honey. I’ve also found that adding just 1-2 drop of vanilla is pretty great, too. Thanks for the simple, yummy, healthy recipe!

Where does the 23g of protein come from? My natural non fat yoghurt only has 8.5g of protein per serve. I have checked many brands and only certain brands of individual size yogurts have anywhere near that amount of protein. And Blueberries only have a negligible amount of protein. I think there's a error here.
