The panels each comprise an inner heating layer mounted on a mounting board, a spacer such as a spaced pair of paperboard sheets with an intermediate corrugated piece, and an outer microwave shield. The heating layer is in direct contact with the food items and can comprise a metallized film. The microwave shield can be a foil such as aluminum foil.
