I know everyone has their own way of doing it, but I figured I'd share mine. Since I was chopping lunch for K, I grabbed the camera. I have a Pampered Chef food chopper from who knows when, but I know Oxo has one at Target and other brands are around as well. (sorry for the sun) (ETA: the bologna sandwich was mine.
Here's a pic of her Pasta Primavera and her broccoli after being chopped. I made sure to get the Penne noodle so you'd have a size reference.
And here's her eating it so you can see how tiny the pieces get.
and just for fun, her Munchkin suction bowls. Great product, huh? They stick for about 2 minutes.
