Not a capital offence surely?
2 leeks, washed and sliced
100g blue cheese, crumbled (David is not a fan of blue and goat's cheese works very well too)
50g walnut pieces (and for once, with Kit no longer living here, I went out on a limb and added these too)
Heat the oil in a frying pan and fry the courgettes, in batches, cut side down. Transfer to an oblong ovenproof dish.
