We have a pannini maker that makes lunches fun again. I also like to make homemade chicken nuggets and freeze them, and homemade chips, which always go down a treat .
Pizza is handy as well, just make them out of an English muffin base.
Our daughter is a very picky eater who doesn't have a big appetite, the two of us are the same way, so she tends to be more of a grazer.
