   *Transportation tips: Transfer the sandwiches to a covered plastic container to transport them to the picnic, and then simply pass around the container to serve. To keep the bread from drying out, when stacking the sandwiches in the container, lay a sturdy, barely moistened paper towel between each layer and another one over the top.
