if you have the right sort of courgette , you could grow some on to marrows....ie really big courgettes. Some types have been created to produce courgettes , but some are really just cut as baby marrows . If you grow them on to be marrows they store in a shed for ages , through most of the winter. They are really lovely cooked as stuffed marrow . I use mince , but you could use whatever you want . Plenty of salt and pepper and they are to die for .....You can also serve it diced with a roast if you like . I know as a kid I grew loads , stored them in the garden shed and we had them right through the winter , 2 or 3 a week . Good for a family of 9.
cheers
