Extrudable materials are provided in a pre-packaged disposable container. The container includes a first end having a dispensing aperture and a second end containing a shuttle that may be advanced within the container to dispense or extrude the contents. The shuttle is advanced towards the dispensing aperture in incremental amounts corresponding to the desired amount of contents to be extruded. Advancement of the shuttle may be accomplished using an extruding device integral with the container or from a separate extruding device. The container and shuttle are configured such that when the shuttle is advanced to a position proximate to the first end, the shuttle is locked so as to prevent rearward retraction of the shuttle back to the second end of the container. When the desired quantity of food has been prepared, the user recycles or disposes of the container, eliminating or greatly reducing the necessary amount of required cleanup.
