Ha Allypallywasp I have six plants. We had four last year and they didn't do much. This year is another story.
Spaghetti with fried courgettes, garlic and grated pecorino is our favourite.
Courgette and chickpea curry - there are lots of very similar recipes online.
Australian Women's Weekly Zucchini Slice - basically a crust less quiche
Courgette fritters - again lots online, we prefer a gram flour batter, not an egg and plain flour one.
Roast courgette and feta - roast the feta as a block surrounded by courgette chunks, all basted with olive oil and honey,
Obviously ratatouille, which freezes well
And in desperation I've sliced, roasted and frozen quite a few for winter lasagnes
My children can eat a cucumber a day so no advice there!
