Secret Sandwich (Lunch Box Surprise)

For our 5 year olds lunch box for either snack time or lunch for his first year at kindergarten that are reasonably healthy but will bring a smile to his face when he finds them. Kids tire of the same old sandwich, so I came up with this as a new and fun way to make sure he doesn't skip his sandwich! I was surprised at how much lunch meat and cheese I was able to get in the muffin! If you child likes lettuce you could stuff some of that inside as well. You could actually fill the hole with just about any type of sandwich filling. :)
