Abstract
Abstract Dispenser apparatus for a complete meal includes a refrigerated cabinet in which is disposed a plurality of prepared meal packages which include hot portions and cold portions, the cold portions being protected by foil wrap or other microwave impregnable shield. After a meal has been paid for, the meal package is transferred from the top of a stack and moved to a microwave oven where the hot portion of the meal is warmed by microwave energy. The portion or portions of the meal which are shielded from the microwave energy remain cool so that the meal package, as delivered, includes warm portions and cool portions.
