Frozen Greek Yogurt Recipes?

Does anybody have any good frozen Greek yogurt recipes? I'm thinking of getting an ice cream maker and am wondering how I might use it for protein-type snacks.

I'd particularly like recipes that don't rely on artificial sweeteners or sugar free syrups, if such things exist.

Check out Eggface's website..she has lots of protein ice cream recipes.
