Spread 'raw' cashew nuts out on a baking tray.
Roast in oven for a few minutes turning every so often (you need to keep a close eye as timings vary). Take out and allow to cool a bit.
Drizzle with Olive Oil and add salt. Store.
They are absolutely delicious and this was you also control the amount of salt on them. The only problem is, will they last til Christmas. (I think not, as jar has been half emptied already!).
