Ask Blake at Crimson Caravan Camp, Ruby Nash in Primm, and Fitz at Grub n' Gulp Rest Stop about the possibility of meat supply contracts with Camp McCarran.

Detailed walkthrough
Farber will give you the Meat Vendor List.

Note: Having 40 (50 on Xbox 360) Barter will convince Blake at the Crimson Caravan to trade for some of the overstocked vegetables. Alternatively, having a Speech of 70 can bypass the need for money as well.

Note: Once doing the above note you need not to contact the rest of the vendors.

Note: Having a Speech of 70 can convince Blake to give the NCR a deal on the price.

Farber will also give the Not Worth a Hill of Corn and Beans unmarked quest.

Farber will complain about lack of spices to go with the food and suggest that NCR scientists may know of an ingredient that will enhance the taste.

During your quest in Vault 22 you can find notes of spice tests being carried out on animals, resulting in improving their mood. A jar with food additive can be found nearby. You can give it to Farber for extra exp.
