A food service system for serving a standard meal to a group of people. The various food items that go together to make up the standard meal are prepared, and meals are assembled by placing the food items on trays so that each tray is one meal for one person. The tray has wells for receiving dishes containing the food items, and some of the wells have electrical contacts connected to contacts on the handle of the tray. A heated food item is placed in a dish having an electric heater that can be energized from the contacts in the well of the tray. A group of the trays is placed into a carrier, and supported on rails by the handles of the trays. The rails are connected to a power supply so that the foods in the electrically heated dishes in the wells having electrical contacts will be heated, and others will not be heated. The carrier is ventilated to remove excess heat to prevent heating the cold foods.
