Courgette & Lemon Drizzle Loaf with Pistachio

I was given a slice of this a while back and when my friend told me what it was, I thought … courgettes in a cake, really? But when I took a bite into that beautifully moist and flavoursome crumb, I was sold. The fact that courgettes are kind of one of your ‘five a day’ is an added bonus! Choose the green pistachios in the shops, not the brown dry shrivelled ones. If you can’t find them then just leave them out, or substitute with hazelnuts or walnuts.
