I use the food chopper constantly! Whenever making ground meat I chop up broccoli and carrots really fine and mix it in. It doesn't affect the taste and we all get a little more veggies in our meal.
I make puddings and jello in the 1 cup prep bowls... less waste that way.
We feed our son (19 months) pretty much whatever we're eating. He'll either eat it or he won't. It not as much because he doesn't like it, but more because he decides he's not going to eat. The biggest adjustments I'll usually make is putting aside a portion before putting in seasoning, if I'm making something spicier.
He enjoys the Chicken Penne, and anything with ground beef or meat. Pasta dishes get a bit messier, but it's not a big deal because bath time is fairly soon after dinner.
