Courgette bread will use at least some of them. Freezes really well too. A
fine savoury crusty bread with an unusual pale green crumb - very showy for
light lunches, toasts and sandwiches. Non english-speakers call it zuccini
bread.

One of my favourite uses is to grate it into cake + muffin mix - produces a
batch of impressively green sweet snacks.
