Nadiya uses a crisp potato rosti mxture as the base of this cheese and chive quiche. Genius! You could use gluten-free flour to make it gluten-free too. Preheat the oven to 180C/160C Fan/Gas 4.

I’ve delved so heavily into potato recipes over the last two years that ... I always keep them aside to use in a veggie stock or a soup, or even fry them for a crispy snack.
