Courgette Recipes Please!

Our courgette crop this year has been practically non-existent, but luckily Martin's sister has been able to keep us well supplied.  Her courgettes have tended to be a little on the large side mind you - more like marrows - and today's offering has left me feeling rather daunted:

[The egg is for scale - the red thing is our first 'ripe' Scotch Bonnet chilli, which I'm also somewhat apprehensive of despite its small size!]

If anybody has any good courgette recipes, would be glad of suggestions . . .

Update: found a good use for overgrown courgettes on Twitter (thanks Amanda!) - apparently they are just the thing for scaring off your charging black bear - I guess I could try throwing it at a marauding bunny . . .
