Preheat the oven to 350 F. Layer half the phyllo dough in a 9-inch square baking pan (or use a 9-by-13-inch pan), brushing with half the melted butter and scattering crumbs between layers.
In a bowl, combine the chopped almonds, 2 Tablespoons sugar, orange peel, cinnamon and nutmeg. Place the nut mixture over the layers of dough.
Cover the nut mixture with the remaining phyllo leaves, separating them as above with melted butter and crumbs.
Brush the top layer with the last of the melted butter. Score the dough with the tip of a sharp knife into squares or rectangles.
Bake for 30 minutes. Raise heat to 400 F. and bake for another 15-20 minutes, or until the top is golden brown. Remove from the oven and set aside.
