Notes: These delicious roasted sweet potatoes can accompany meat, fish or vegetarian dishes. We love our sweet potatoes; Chinese farmers would cook these over charcoal buried in the earth - something my grandparents did, too. Now the modern Chinese family in China would have an oven, which means they can slow-roast sweet potatoes to perfection!
1) Preheat an oven to 180°C.
2) Place the olive oil, sea salt, crushed dried chilli flakes and black pepper into a roasting tin. Add the sweet potato slices and turn them to coat in the seasoned oil. Roast in the oven for 20 to 30 minutes, depending on the thickness of your chips. Serve immediately.
