Kinda both. This was a long time ago so things have probably changed and some of it may have just been my store. But we'd make a bunch of burritos an hour or more before opening and put them in this thing like a mini fridge but kept stuff warm. And the top layer that would congeal on the beef was so gross. Then it came in this big plastic pouches you plopped into tray to warm up. But I know a few years ago there was a stink about how much of it is really beef so they've probably changed that.
