Name That Vegetable!

Aaaaaand once more, Ladies and gentlemen, Welcome to another exciting episode of Name That Vegetable! 

 What is it? It looks like a stick.You can peel it. It doesn't taste like much at all. Which only I can attest to, as I was the only one that actually ate the stuff. (OK, Steve tried it.)

For the record, it's easy to find out what something looks like when you have the name, but working backwards, it's a lot harder. I have no idea how to find out what something is by looking at it.

This message has been brought to you by my CSA! Which we will soon be dropping due to excessive cost and excessive parsnips.
