* The casserole may be prepared, covered and refrigerated for up to 8 hours. * As an alternative to puff pastry, you might try using sheets of filo dough, overlapped to make the bottom and top crusts. I have also baked this dish in a pie pan using filo dough. One way to cut down on the calories in this dish is to omit the bottom crust entirely. This is a very flexible recipe. Other vegetables can be substituted for the spinach, and other ingredients like sauteed garlic and mushrooms can be added. : Difficulty: moderate. : Time: 30 minutes preparation, 1 hour baking and cooling. : Precision: approximate measurement OK. : Robin Harris Foster : AT&T Information Systems, Lincroft New Jersey, USA : ihnp4!mtuxo!rfoster : The apple never falls far from the tree : Copyright (C) 1986 USENET Community Trust
