Not Worth a Hill of Corn and Beans

 is a unmarked quest in Fallout: New Vegas.

Walkthrough
This quest is given by the cook Cpl. William Farber on the Concourse at Camp McCarran. He asks you to help fix the food processor. You can either jury rig the fix (with a repair of 80) or find these items:
 * 2 pilot lights
 * 2 pressure cookers
 * 2 conductors
 * 2 firehose nozzles
 * 4 fission batteries
 * 2 steam gauge assemblies
 * 2 sensor modules
 * 5 scrap metal
 * 1 pot (2 pots in inventory needed! See "Bugs" below)

The Steam Gauge Assemblies can be bought at Gibson Scrap Yard (and some of the other hard to find items ) Most, if not all, the items on the list can be found in Vault 11. Cerulean Robotics in Freeside also has most of the items needed.

The reward given is a discount on his (limited) food merchandise. Note that this quest does not count towards quest completion, and you do not receive any experience for completing it.

Bugs

 * The list he gives you says 1 (one) pot, but you need 2 (two) pots to actually fix it. Upon completion it will remove only one pot but you must have two in order to start repair. Also its says you do not have all the items needed when you do.
