Ham sandwich.

That would be Item #130001 from Integrated Food Services.[1] "Today IFS and their affiliates own and operate a state-of-the-art facility which includes two USDA processing plants, a wholesale bakery and a dry warehouse which total over 100,000 square feet on five acres. We are located in the greater Los Angeles area, almost equidistant from downtown, LAX and the Port of Los Angeles." Most of the prepackaged sandwiches in Southern California come from those plants. Here's an automated sandwich assembly line.[2]
