Abstract

Abstract Heat-and-serve packages of precooked sausage and the like include a disposable, heatable tray formed with foldable sides from sheet material capable of retaining melted fat, with links or patties of precooked or prefried sausage or the like laid flatwise on the bottom of the tray. The sides of the tray are folded downwardly and inwardly over the margins of the precooked sausage links or patties and the assembly is enclosed in a disposable film envelope, being preferably evacuated and hermetically sealed. In use, the outer film or envelope is removed, the sides of the tray are folded up and the tray is inserted in an oven, or placed on a hot plate whereby the sausage contents are heated and acquire the characteristic flavor of sausage fired or cooked in the usual manner. Single or multiple trays may be sealed in an envelope formed of barrier film. A single tray may be folded and multiple trays may be separable into smaller trays. While the invention is particularly useful for precooked sausage, other heat-and-serve items that exude or release fat or liquid on heating may constitute the contents.
