Abstract: An open grill assembly, with a radiant heating sheet, can be assembled together into a rigid grill, with rods forming a frame supporting the radiant sheet and the grid in a spaced apart relationship. The components can be disassembled into a compact bundle, preferably a flat bundle. When assembled, in a preferred embodiment, the radiant heating sheet is adapted to rest on the top of the burner, so that the rods forming the frame need not touch the ground, allowing a single, economical design to be used with most, and perhaps all, commercially available burners. In operation, the burner heats the radiant heating sheet and radiant heat from the sheet cooks food on the grid.
