I used my own puff pastry for this, and assembled the ingredients - the full pound of puff pastry, softly scrambled eggs (10 of them - yow!) with herbs, roasted red peppers, sauteed spinach, sliced Swiss cheese and sliced ham. Three-quarters of the pastry is rolled out, fitted into the buttered pan (8.5" springform), and then chilled to firm up. The ingredients are layered in as a sort of mirror image, with eggs on top and bottom, spinach, ham, and cheese inside those, and peppers in the middle. Pretty simple to put together, once you get all the prep work done.
The remaining dough is fitted on top, and then egg wash applied. You chill the assembled creation for 30-60 minutes, and then bake for an hour and a quarter (I think I went even a little longer), until puffed and golden.
