Abstract
Abstract A tray supporting individual thermally insulated casseroles of food portions for serving complete meals such as entree food to be cooked and frozen and chilled side dish food. The entree and individual side dish food portions are each placed in separate casseroles in chilled or frozen condition. Each casserole thermally encloses the separate food portions and the thermal insulation of the casserole and the initial low temperature levels of the chilled or frozen food retains the food in the casseroles without degradation or pathogenic effects for storage periods up through several hours and retains the side dish food without pathogenic degeneration during the time the entree food is cooked in separate casseroles.

243 words
A device for storing and selectively cooking food comprising: a. an uninsulated container; b. electric circuit means contiguous with said container; c. a plurality of thermally and electrically insulating trays removably disposed in said container having electrical conducting means contiguous therewith and connected to said electric circuit means; d. a plurality of thermally insulated heating casseroles containing chilled or frozen entree food to be heated, each heating casserole having a heating element connected with said electrical conducting means, at least one of said heating casseroles disposed on one of said trays; e. a plurality of thermally insulated unheated casseroles containing side dish food placed therein in chilled and frozen state, said unheated casseroles disposed on said trayS in spaced-apart relationship with each other and said heating casseroles; and f. timing means interconnected with said circuit means and electrical conducting means to energize the heating elements of selected heating casseroles in predetermined on-and-off intervals to cook the frozen or chilled entree food therein, the thermal insulation of said heating and unheated casseroles and the initial temperature levels of said chilled or frozen entree and chilled and frozen side dish food preventing degradation of the food therein for storage periods of up to 3 hours and preventing degradation of the frozen or chilled entree food in said heating casseroles not selected for cooking and of said frozen and chilled side dish food in said unheated casseroles when said selected heating casseroles are energized for cooking.
