In some embodiments, the sauce tray is part of a lid system that also creates a separate cavity within the interior volume of the food container to store another food product. ## Claims ### Claim 1 A combination, comprising: a food container; and a sauce tray defining multiple openings through a base surface and configured to be positioned in either a first orientation or second orientation on top of the food container, wherein (a) in the first orientation, the sauce tray effectively forms a dome over the food container, (b) in the second orientation, the sauce tray effectively forms a bowl that encroaches into an interior volume of the food container, and (c) in both the first orientation and the second orientation, the sauce tray is configured to receive and retain a container of dipping sauce through each of the multiple openings through the base surface of the sauce tray, with an upper flange of the container of dipping sauce engaging the base surface of sauce tray. ### Claim 2 (depends on 1) The combination as recited in claim 1, wherein the sauce tray defines a circumferential groove that engages a rim of the food container when the sauce tray is in the second orientation. ### Claim 3 (depends on 2) The combination as recited in claim 2, wherein the rim of the food container has a circular shape, and the circumferential groove defined by the sauce tray has a corresponding circular shape. ### Claim 4 A lid system for a food container, comprising: an insert tray having a bottom wall and a continuous side wall that collectively define an interior cavity with an open top, said insert tray being received in an upper portion of the food container, thus creating a separate cavity within an interior volume of the food container; and a sauce tray, said sauce tray defining one or more openings through a base surface, and said sauce tray being placed over the insert tray on top of the food container, wherein the sauce tray is configured to receive and retain one or more containers of dipping sauce through the one or more openings through the base surface of the sauce tray; wherein the sauce tray includes multiple downwardly extending appendages that are spaced at intervals around a periphery of the sauce tray with each of these downwardly extending appendages defining a lateral recess, and wherein the insert tray includes multiple tabs that are adapted to engage the lateral recesses defined by the downwardly extending appendages of the sauce tray, thus locking the sauce tray to the insert tray. ### Claim 5 (depends on 4) The lid system as recited in claim 4, and further comprising a paperboard insert for selectively closing access to the separate cavity created by the insert tray. ### Claim 6 (depends on 5) The lid system as recited in claim 5, wherein the paperboard insert rests on one or more internal ledges defined within the interior cavity of the insert tray. ### Claim 7 (depends on 4) The lid system as recited in claim 4, wherein, the sauce tray effectively forms a dome over the insert tray on top of the food container. ### Claim 8 (depends on 4) The lid system as recited in claim 4, wherein the insert tray includes an upper circumferential flange for engaging a rim of the food container. ### Claim 9 (depends on 8) The lid system as recited in claim 8, wherein the rim of the food container has a circular shape, and the upper circumferential flange of the insert tray has a corresponding circular shape. ### Claim 10 A combination, comprising: a food container; an insert tray having a bottom wall and a continuous side wall that collectively define an interior cavity with an open top, said insert tray being received in an upper portion of the food container, thus creating a separate cavity within an interior volume of the food container; and a sauce tray, said sauce tray defining one or more openings through a base surface, and said sauce tray being placed over the insert tray on top of the food container, wherein the sauce tray is configured to receive and retain one or more containers of dipping sauce through the one or more openings through the base surface of the sauce tray. ### Claim 11 (depends on 10) The combination as recited in claim 10, in which an upper flange of each of the one or more containers of dipping sauce engages the base surface of sauce tray. ### Claim 12 (depends on 10) The combination as recited in claim 10, wherein said sauce tray defines multiple openings through the base surface. ### Claim 13 (depends on 10) The combination as recited in claim 10, wherein the sauce tray effectively forms a dome over the insert tray on top of the food container. ### Claim 14 (depends on 10) The combination as recited in claim 10, wherein the insert tray includes an upper circumferential flange for engaging a rim of the food container. ### Claim 15 (depends on 14) The combination as recited in claim 14, wherein the rim of the food container has a circular shape, and the upper circumferential flange of the insert tray has a corresponding circular shape. ### Claim 16 (depends on 10) The combination as recited in claim 10, and further comprising a means for locking the sauce tray to the insert tray. ### Claim 17 (depends on 10) The combination as recited in claim 10, wherein the sauce tray includes multiple downwardly extending appendages that are spaced at intervals around a periphery of the sauce tray with each of these downwardly extending appendages defining a lateral recess, and wherein the insert tray includes multiple tabs that are adapted to engage the lateral recesses defined by the downwardly extending appendages of the sauce tray, thus locking the sauce tray to the insert tray.
