Richard's offerings have caused us to be more adventurous with unfamiliar foods. White Turnips and Okra (I didn't even know what it was when he gave me a bag) were clear WINNERS. For our taste, Senposie, not so much, although it is absolutely amazing in an omelet.
If there's any downside, it's that I still have to go to the grocery store for some of the more "common" vegetables. That being said, I understand there's a limit to what one man (and his dog) can do.
