Blueberry treat by mail

[elainegrey]

I would like to bake something with blueberries to send to colleagues in another state once my blueberries start coming in. I *can* dehydrate the blueberries, but that seems to diminish the point. I believe a colleague needs gluten free, and i would also want to make the treats vegan. If i wasn't sending by mail, it seems a tart would be nice. I think i have tiny tart pans if that's the best idea....

Ideas welcome!
