A healthy snack that’s super easy and uses up those stray apples in the fruit and veg drawer. Preheat the oven to 90°C (200°F). Thinly slice red apples (I used braeburns, but any would do) by hand or with a mandolin – two apples produces a good snack portion for one. Lay the slices out neatly on baking sheets lined with greaseproof paper and pat dry with kitchen towels. Pop in the oven and bake for an hour. Carefully peel the crisps off the paper and eat immediately (or store in an airtight container for later).
