Purple!

I had a business lunch today, so we met up at Mint Tea and I popped a pill so I could have a gyro.  The waitress brought it out to me and it was beautifully presented:

SO PURPLE!

But I had no idea what the purple stuff could possibly be.  Me being me, however, I took a brave bite and discovered...

Potato salad.

Heh.  Yeah, it made me laugh.  And then eat more, because it was really freaking good.
