The system comprises at least one generally circular dish having a top surface for holding the foods that are to be served warm, and a bottom surface, an electrical heating element in the dish for heating the foods on the top surface of the dish, and first and second electrical contacts on the bottom surface of the dish for supplying electrical energy to the heating element. The system further comprises at least one tray, having at least one generally circular well therein for receiving one of the generally circular dishes, and at least one aperture in the well for exposing the first and second electrical contacts on the bottom surface of the dish when the dish is seated in the well. The dish includes at least one foot and the well in the tray includes at least one stop for orienting the dish in the tray to orient the first and second contacts with respect to the aperture. The system further comprises a support for each tray, each support including first and second electrical power supply contacts for each dish, configured to make electrical contact with exposed first and second electrical contacts on the dish received in the well in a tray supported on the support.
