If you want a vegetarian dish to make an impact on the table, this does the job – it looks great and has really complex flavours.
Heat the oven to to 220C/425F/gas mark 7. Put the squash and onions in a large bowl, add three tablespoons of oil, a teaspoon of salt and some black pepper, and toss well. Spread, skin down, on a baking sheet and roast for 40 minutes until the vegetables have taken on some colour and are cooked through. Keep an eye on the onions: they may cook faster than the squash, so may need to be removed earlier. Remove from the oven and leave to cool.
