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.
Gluten-free flours are a little harder to work with, but worth mastering. Keep the dough dry; although slightly more difficult to handle, it gives a crisper, 'shorter' crust for quiches and pies.
