Too late to plant fruit and veg?

[BooksAndChooks]

Our cucumbers are done, so we have some space in the greenhouse. We are working our way through the potato patch so there's also some space there. Is there anything I can plant this late in the year?

Lettuce

lamb's lettuce as well

And spinach

Never ! Think I've attached a list , I'm putting potatoes where I've dug up potatoes, trying swede etc
