OH MY GOD. This is OUTSTANDING. I am so envious now, you have no idea. ;) If you end up with a few extra bars of dark chocolate with hazelnuts, I'll send you some black beans in return (assuming it's legal to mail them)!
Also, the one good thing about choosing food based on the packaging is that you don't get tied to one particular brand or type; you get to try out every variety of mystery cheese or yogurt or breakfast cereal. The disadvantage is that it's hard to remember which kinds you liked and didn't like..
