Abstract
A food tray has a lower tray containing a first food product and an upper tray nested stably at least partly inside the lower tray, with the upper tray containing a second food product. An air permeable interface is provided between the upper tray and lower tray to allow venting of steam from the lower tray during cooking. A cover is provided for the food tray. Each of the lower tray and the upper tray are formed of a material that is suitable for use in a microwave or conventional oven. Various constructions may be used to create the air permeable interface, such as lugs, ledges and lips. The upper tray may sit above the lower tray. The trays are nested loosely for case of removal of the upper tray from the lower tray. Various configurations of cover may be used such as a sleeve, carton or lid. The upper tray may contain the higher value food product.
