I have a question for those of you military folks that actually worked with the food, not just breaking eggs, doing dishes, and peeling potatoes; grade D beef was mentioned - did you ever see a “ground beef” or beef-like-mystery-meat product that came in the form of paste, layered out on a plastic sheet, and then rolled up like a jelly-roll; boxed up and received frozen, to be thawed, unrolled, and worked with from that state in any/all applications that would call for ground beef?
