A food preparation appliance, comprising: a reversible rotary power source disposed in a base; a slicing disc rotatably coupled to the source of rotary power, the slicing disc having a radially extending slicing blade formed on one side thereof configured to perform a slicing operation and a plurality of radially extending shredding blades disposed oppositely to the slicing blade on the slicing disc configured to perform a shredding operation; a slice selector disc disposed beneath the slicing disc and rotatably mounted on the base such that it can be rotated to select one of a plurality of discrete positions (1, 2, 3), a first of the discrete positions being selected for the slicing operation, a second of the discrete positions being selected for the shredding operation and a third discrete position being selected for a dicing operation, and the slice selector disc includes an associated first food processing configuration formed in the slice selector disc corresponding to the first discrete position being selected for the slicing operation, an associated second food processing configuration formed in the slice selector disc corresponding to the second discrete position being selected for the shredding operation, and an associated third food processing configuration formed in the slice selector disc corresponding to the third discrete position being selected for the dicing operation; wherein the slicing disc is automatically rotated in a first direction by the rotary power source when the first and third discrete positions are selected on the slice selector disc corresponding to the slicing and dicing operations and the slicing disc is automatically rotated in a second direction by the rotary power source when the second discrete position is selected on the slice selector disc corresponding to the shredding operation. a reversible rotary power source disposed in a base; a slicing disc rotatably coupled to the source of rotary power, the slicing disc having a radially extending slicing blade formed on one side thereof configured to perform a slicing operation and a plurality of radially extending shredding blades disposed oppositely to the slicing blade on the slicing disc configured to perform a shredding operation; a slice selector disc disposed beneath the slicing disc and rotatably mounted on the base such that it can be rotated to select one of a plurality of discrete positions (1, 2, 3), a first of the discrete positions being selected for the slicing operation, a second of the discrete positions being selected for the shredding operation and a third discrete position being selected for a dicing operation, and the slice selector disc includes an associated first food processing configuration formed in the slice selector disc corresponding to the first discrete position being selected for the slicing operation, an associated second food processing configuration formed in the slice selector disc corresponding to the second discrete position being selected for the shredding operation, and an associated third food processing configuration formed in the slice selector disc corresponding to the third discrete position being selected for the dicing operation; wherein the slicing disc is automatically rotated in a first direction by the rotary power source when the first and third discrete positions are selected on the slice selector disc corresponding to the slicing and dicing operations and the slicing disc is automatically rotated in a second direction by the rotary power source when the second discrete position is selected on the slice selector disc corresponding to the shredding operation.
