1 . Stage

Preheat the oven to 425 degrees F (220 degrees C).

Heat oil in a skillet over medium-high heat. Add onion and saute until soft, 5 to 7 minutes. Remove from heat.

3 . Stage

Mix hazelnuts, Brazil nuts, bread crumbs, parsley, oregano, sage, salt, and pepper together in a bowl. Add tahini and soy sauce; add enough broth to give it a moist, stuck-together texture. Add sauteed onions, spinach, and corn; mix well.

4 . Stage

Mix flour, baking soda, and salt for crust together in a bowl.

5 . Stage

Heat 3/4 cup water in a small pot and melt in shortening until almost boiling. Add to the flour mixture a little at a time, until combined, mixing well. Add extra boiling water if the mixture is too dry.

6 . Stage

Put 2/3 of the dough into a 7-inch springform pan and push into a crust shape. Add filling, pushing down well.

Roll out remaining dough to make a pie lid. Press onto pie. Glaze top with beaten egg white and cut a small "x" in the center to allow steam to exit.
