Encontrei duas explicações para este provérbio:

1) "According to Hans Schemann's German/English Dictionary of Idioms, 'kohl' is used in several German phrases to indicate rubbish, nonsense or boring crap (I paraphrase). So 'so ein Kohl' ("such a cabbage") means 'what a load of rubbish.' And 'aufgewärmter Kohl' means 'a boring old story' (literally, I guess, 'reheated/warmed over cabbage')."

This certainly seems related, conceptually if not historically, to the English expression "I don't chew my cabbage twice," which is better-attested than the way I first heard it as a lad, "I don't cook my cabbage twice" (when asked to repeat oneself). And this role for cabbage in our discourse is of ancient origin, as Dan has discovered:

"Crambo, earlier crambe, comes from the Latin phrase crambe repetita 'cabbage reheated, re-served,' a phrase in Juvenal’s 'Seventh Satire' ('Reheated cabbage kills teachers') referring to unimaginative writing. The Latin crambe is a borrowing from Greek krámpa, a kind of cabbage. Crambo, the rhyming game, entered English in the mid-17th century; crambe, inferior rhyme, in the early 17th." As Ramsay (1918) has it, Juvenal goes on to say "Served up again and again, the cabbage is the death of the unhappy master!" And Juvenal identifies as a Greek proverb, “Dis kramb thanatos" (twice-cooked cabbage kills us).

Entry:
cabbage twice cooked is death[b] (Greek) Some things, like cabbage, should be discarded if not consumed or otherwise dealt with at once...

2) Some Cabbage Chemistry or ~ or Why does cabbage "stink" when it is cooking?

Modern science has explained such emissions as a release of hydrogen sulfide. n fact, the longer cabbage is cooked, the greater the amount of hydrogen sulfide produced. This is not exactly news as there is an ancient Greek saying "Cabbage twice cooked is death." Cooks advise boiling cabbage with a piece of chili pepper "to diminish the unpleasant odor." Despite these olfactory drawbacks, cabbage has been quite popular for the last 2,500 years. -- The Pickled Pig, Facebook
