The insert of claim 6, further comprising a stand off bracket mounted on said rim between said rim and said tile, said stand off bracket forming a portion of said tile stay and a stop to space said tile from said rim along at least one edge of said tile. 8. The insert of claim 5, wherein said support structure is formed of at least one panel, and comprises: said at least one panel having a plurality of arched cut-outs; said at least one panel defining a plurality of legs with said arched cut-outs disposed between adjacent said legs; and said at least one panel further comprising said rim extending transversely from said plane on an opposite side of said plane from said plurality of legs. 9. An insert for a barbeque having a grill and for baking a pizza comprising: a frame having an upper surface generally defining a plane generally parallel to the grill, a plurality of legs connected to the frame for elevating and supporting the frame above the grill, and a ceramic or stone tile supported on the frame at the level of the plane so that an open space is defined between tile and the grill by a distance which is sufficient to reduce uneven heating of the tile and damaging thermal stresses to the tile, the tile and frame being sized so that the frame defines an open slot along one edge of the tile communicating freely with the grill, so that debris on the tile can be scraped from the tile and disposed of into the open slot and into the grill below; a back splash connected to the frame and extending above the level of the plane to prevent excess slippage of the pizza on the tile when it is being removed from the tile; a thermometer thermally coupled to the frame in a position so that the thermometer provides an indication of the baking temperature achieved at the location of the tile. 10. An insert for a barbeque for receiving a pizza on said insert in the barbeque, said insert comprising: at least one tile; a rack having an upper surface generally defining a plane, and having at least one opening in said upper surface, wherein said rack supportingly receives said tile; a support structure supportingly connected to and extending generally away from said rack; and a thermometer selectively and rigidly connected to said rack; wherein said tile is supported by said rack and said support structure, and wherein said rack and said support structure are adapted to support said tile at a predetermined distance above a grill of said barbeque, and further comprising a woodchip tray separate from, yet associated with said insert; wherein said woodchip tray is selectively placed in said barbeque with said insert to burn woodchips in order to add a smoked flavor to a pizza being baked on said insert. 11. An insert for a barbeque having a grill for receiving and baking a pizza on said insert, said insert comprising: a tile stay having an upper surface generally defining a plane, a plurality of legs connected to said tile stay for elevatingly supporting said tile stay, wherein said plurality of legs have proximal ends connected to said tile stay and distal ends spaced from the tile stay to space said tile stay from the grill of the barbeque on which said insert is supported by a predetermined distance to define an open space between the grill and the plane, and at least one ceramic or stone tile supported on said tile stay at the level of the plane so that the open space defined between the plane and the grill is sufficient to reduce the possibility for uneven heating of the tile and damaging thermal stresses to the tile, the tile and tile stay being sized so that the tile stay defines an open slot along one edge of the tile communicating freely with the grill, so that food debris accumulating on an upper surface of the tile can be scraped from the upper surface of the tile and disposed of into the open slot and into the grill below. 12. An insert for a barbeque for
