Not necessarily together!
Our veg box has had butternut squash in it every week for ages, and we now have FOUR languishing in the veg tray. It's such a faff to peel and chop so I almost only ever roast it whole. Which is very nice, but dh is fed up with it as it reminds him of weaning food (which isn't surprising, as that's what we used it for with each child).
And as for kohl rabi - I thought I had a fairly wide knowledge of food, but I didn't even recognise it in the box, and I can't find a single recipe for it in any of the 8 recipe books I have on my shelf ATM. So what do I do with it?
