You can make your own healthy crisps using sweet potatoes, beetroot and parsnip, a vegetable peeler or a mandolin, a little oil and seasoning. At a fraction of the price of well-known brands, it’s not only the kids who’ll love them.
Preheat the oven to 180°C/gas 4. Slice the vegetables very thinly – a mandoline slicer is perfect.
Spray a little oil over a baking sheet and arrange the vegetable slices ensuring they don't overlap. You may need to make them in separate batches depending on the size of your oven.
