Honestly, when it comes to catering Delta's caterers are really not up to the task.
I usually pre-order a MOML (Muslim) meal and always get a VGML meal (the last time the little slip of paper had MOML written in marker OVER the "VGML" written in pen...been meaning to post it for a chuckle...)
The VGML/MOML meals are usually pretty disgusting....
