Salt and vinegar is a classic combination – but, while crisps may deliver on the flavour front, they don’t offer any health benefits. For a snack that will still hit the spot, empty a drained tin of chickpeas into a pan, add a pinch of salt and pour over enough white wine vinegar to cover, plus a little more. Bing to the boil for just 30 seconds, then remove them from the heat, cover and set aside. After half an hour, drain your chickpeas, lay them out on a baking sheet, drizzle with a little olive oil, and add a sprinkle of salt. Finally, roast for 20 minutes at 200°C (400°F), shake the tray, then roast for another 10-15 minutes until golden.
