The Taste website has some good options for quiche. I make the Impossible Quiche option which has flour, milk and eggs and whatever meat / veg you want to add but no pastry. So kind of like a fritatta.

I like the idea of a pastry less quiche!

I normally buy a savory flan from the frezzer department mix spinach, ricotta and fetta together aswell as some eggs and wack it all together thek cook for about 30mins
