Artdecogran that's a bit like the hay eating horse question at school, you know the one "if one horse can eat x bales of hay in y days, how many days do z horses...?etc"..and I refer you to the answer I wrote back then "impossible to answer!.Some horses eat more than other horses" Perfect sense to my 12yr old brain.. But back to your cabbage, using the same principle...how big was it? Me, tho, I'd eat what I want for that meal and shred,blanch, portion and freeze the rest Sorted!
Getting through a family sized fruit and veg box has been a real challenge. I'm down to a large white cabbage (very nice chopped with apple and sultanas as salad) and a sad looking swede that I keep meaning to cook and mash.
