I have wondered this for a while, and although I think I know the answer I figure I would ask it anyway.

I fly a lot of transatlantics in WT and while the outbound leg from LHR has food that is almost edible (although it has gone drastically down hill from when I last flew BA regularly) the return legs from the states I wouldn't feed to my cat/worst enemy. So I was wondering are any of the other special meals, Kosher, Hallal etc any less like warmed up dog food (with rice)?
