I'd never made sandwich balls before, had never heard of them until a couple of weeks ago when they were posted as an upcoming tutorial on Bento Blog Network. They are exactly what they sound like: bread balls with sandwich filling rolled into the middle. I wanted to try making some to take part in this week's Bento of the Week meme, but wasn't sure any of my picky sproutlets would want to eat them... so I made them for an after-school snack instead of a packed lunch. And since this snack wasn't going anywhere, I decided to have a little fun with it, and made a peanut butter sandwich ball banana split :
I made a little ice cream cone one for Pickle too:

Twist the plastic wrap at the base of the ball to tighten and compress it.
Unwrap the plastic. Never mind how how messy the bottom looks :)
Flip the ball over so the messy side doesn't show.
Admire your lovely round sandwich ball!
That's basically it. Now you can make something with it.
Or just eat it like a filled donut hole :)
