A plurality of holes may or may not be provided through a lower portion of the tray (e.g., in a lower portion of the sidewall of the tray) to draw combustion air into the air flow portion, below the mesh insert. The system may pre-arrange the fuel in the tray during manufacture, so the user is not required to spread or even touch the briquets, or may be for use with fuel provided by a user. Clean up is very simple, as the entire system can be discarded after a single use, once cooled, as the ash is automatically collected in the bottom of the tray. ## Claims ### Claim 1 A self-contained fuel system for grilling, the system comprising: an exterior tray formed from a non-combustible material, the tray defining an interior; a mesh insert disposed within the interior of the tray, defining an air-flow portion below the mesh insert and a fuel portion above the mesh insert for supporting fuel, with the fuel suspended above the air-flow portion during use; wherein the exterior tray and mesh insert are configured for use with a solid fuel, positioned in the fuel portion of the tray, supported on the mesh insert, during use. ### Claim 2 (depends on 1) The system of claim 1, further comprising a plurality of air flow holes provided through a lower portion of the exterior tray, configured to draw combustion air into the air-flow portion, below the mesh insert. ### Claim 3 (depends on 1) The system of claim 1, wherein the exterior tray does not include any air flow holes provided through a lower portion of the exterior tray. ### Claim 4 (depends on 1) The system of claim 1, wherein the solid fuel is provided pre-packaged with the exterior tray and mesh insert. ### Claim 5 (depends on 1) The system of claim 1, wherein the solid fuel is provided by a user separately from the exterior tray and mesh insert. ### Claim 6 (depends on 1) The system of claim 1, further comprising a kindling material pre-packaged with the exterior tray and mesh insert, for use within the air-flow portion. ### Claim 7 (depends on 1) The system of claim 1, wherein the exterior tray is formed from a metallic foil material, and the insert is formed of a flexible or bendable metallic mesh material, so that the entire system is disposable after a single use. ### Claim 8 (depends on 1) The system of claim 1, wherein the solid fuel comprises charcoal briquets. ### Claim 9 (depends on 8) The system of claim 8, wherein the charcoal briquets are pre-dosed during manufacture with lighter fluid. ### Claim 10 (depends on 1) The system of claim 1, wherein the mesh insert is in the form of a flexible or bendable metallic mesh insert having at least one of a curved surface, an accordion surface, or an undulating waved surface. ### Claim 11 (depends on 10) The system of claim 10, wherein the mesh insert having at least one of a curved surface, an accordion surface, or an undulating waved surface contacts a bottom interior surface of the exterior tray at at least one location, due to the curved surface, accordion surface, or undulating waved surface of the mesh insert. ### Claim 12 (depends on 1) The system of claim 1, wherein openings in the mesh insert are sufficiently small to support charcoal briquets on top of the mesh insert, and sufficiently large to allow ash generated from combustion of the charcoal briquets to fall through the openings in the mesh. ### Claim 13 A self-contained, single-use disposable pre-packaged charcoal system for grilling, the system comprising: an exterior tray formed from a non-combustible metal foil material, the tray defining an interior; a non-combustible flexible or bendable metallic mesh insert disposed within the interior of the tray, the mesh insert providing a non-planar surface within the tray, defining an air-flow portion below the mesh insert and a charcoal portion above the mesh insert for supporting charcoal briquets, suspended above the air-flow portion; wherein the exterior tray and mesh insert are configured for use with charcoal briquets, positioned in the fuel portion of the tray, supported on the mesh insert, during use. ### Claim 14 (depends on 13) The system of claim 13, wherein the exterior tray does not include any air flow holes provided through a lower portion of the exterior tray. ### Claim 15 (depends on 13) The system of claim 13, wherein the solid fuel is provided by a user separately from the exterior tray and mesh insert. ### Claim 16 (depends on 13) The system of claim 13, further comprising a plurality of fire-starter briquets provided with the exterior tray and mesh insert, for igniting the charcoal briquets. ### Claim 17 (depends on 13) The system of claim 13, further comprising a grate configured for placement over a top of the tray for grilling food on the grate. ### Claim 18 A method for using a self-contained, disposable charcoal system for grilling, the method comprising: providing a self-contained disposable charcoal system for grilling, the system comprising: an exterior tray formed from a non-combustible metal foil material, the tray defining an interior; a non-combustible flexible or bendable metallic mesh insert disposed within the interior of the tray, the mesh insert having at least one of a curved surface, an accordion surface, or an undulating waved surface, defining an air-flow portion below the mesh insert and a solid fuel portion above the mesh insert for supporting charcoal briquets or another solid fuel, suspended above the air-flow portion; wherein the exterior tray and mesh insert are configured for use with charcoal briquets or another solid fuel, positioned in the fuel portion of the tray, supported on the mesh insert, during use; igniting the charcoal briquets or other solid fuel; and using the system for grilling; ### Claim 19 (depends on 18) The method of claim 18, wherein no handling of the charcoal briquets or other solid fuel is required by the user during the method, as they are pre-positioned during manufacture in the charcoal portion of the tray. ### Claim 20 (depends on 18) The method of claim 18, wherein the charcoal briquets are positioned in the charcoal portion as: a random pile of briquets, with the briquets randomly oriented in the charcoal portion; or an ordered arrangement of briquets, with the briquets oriented vertically, in rows, in the charcoal portion.
