All you have to do is make diagonal cuts down the sides of your sheet of pastry and criss-cross them over the filling. When the pastry puffs, it transforms into an intricate-looking main dish or dessert.

Served at Christmas dinner, it definitely made the vegetarians at the table feel like we were getting something special! And yet the technique is simple enough to use for everyday meals, not just holidays.
