http://en.wikipedia.org/wiki/Westron English in LotR is a translation of Westron. Therefore, I'm sure the English idiom 'meat is back on the menu' is derived from a more suitable Westron saying. This is common in all translations.
I had the titular line in Star Wars. I was in that scene where that guy is teaching Luke how to fly the Millennium Falcon. Yeah, and I walked by in the background and said "I'm so tired of all these Star Wars"
