When it comes to peanut butter sandwiches, my son isn't big on bread. He prefers the sweet treat served up on a peeled apple that has been cored and halved. I smear some of the creamy spread between and then top with the other half. A fiber and protein packed combo, it's a portable dish that is fit for any time of day. We recently tested the apple idea out on another kiddie staple — grilled cheese. Just take the fruit halves and top them with your kiddo's favorite sliced or shredded cheese and then pop them in a hot oven to melt the protein. Served open-faced or as a sandwich, this simple recipe is a savory winner.
