Abstract: A portable grill easily carried as components, which may be stacked as generally flat parts, to be carried in a compact container, and may be easily assembled without tools and used in various modes. Upper and lower reflectors which are flat rectangular parts when disassembled, are flexed and held in arcuate shapes upon assembly, to form the cooker lid and body, respectively, by rods that engage the edges of the reflectors and mount in holes in the legs. After use, the cooker may be disassembled and transported again. By installing, removing and substituting various parts, the cooking unit may be used as, for example, a grill, a baker, a boiler, a smoker, a steamer, a deep fryer and the like. Provision is made for propane as well as charcoal, wood and other consumable fuels.
