Recipes needed!

So, Alex's flatmates go skipping, and have obtained large quantities of cabbage, parsnip, and potatoes (less of the potatoes - they've been in that box a bit long, I think). As they all have to be out of their rooms by tomorrow morning, these ingredients have been passed onto me as I'm staying in York, and so I must do something with them.

Stew contains all of these things plus meat and swede and onion, and I'm sure that parsnip soup is allowed though making it tasty might be a bit beyond me. Roasted parsnips in maple syrup make the best dessert ever if you're in the mood for it.

I have about eight large parsnips and a cabbage and a half - please give me some ideas of what to do with them!
