Have you tried making your own pastry-less version?
They're so yummy!
I make mine in a silicon victoria sandwich 'tin' - fry off some onions, courgette, broccoli and bacon in some fry-light, pop this in the bottom of the 'tin' and spread out evenly. Then pour on your egg mixture (5 or 6 well-beaten eggs with a couple of tablespoons of water in to loosen it), then on the top I put sliced tomatoes and sprinkle over 2 HExAs of strong cheese, and then me and the OH have half each with some SW chips and salad.
That quiche is syn-free if you use the cheese as a HExA.
I know, I was really surprised considering the Weght Watchers ones are quite low in Points on the packet too.
I love quiche, and I have to say, I love the pastry-less version too. It is a very good subsitute, and that you can more or less eat as much as you like (counting the cheese of course) makes it even better in my book! But then, I am a greedy piggy!
