Reserve 1 egg yolk. In large bowl, combine remaining eggs and egg white with meat, spinach and cheeses.

Prepare pie crust mix as directed for a 2 crust pie. Roll out two rounds, one for top and bottom. Generously flour one side of the bottom crust and place floured side down, into pie pan. Spoon meat mixture into pie crust.

Preheat oven to 375 degrees. Place top crust over meat filling and seal. Cut slits in top. At this point, you can put it in the refrigerator overnight.

In small cup, mix reserved egg yolk with 2 teaspoons of water and brush over top of pastry. Bake 1 1/4 hours or until crust is golden.
