Total Time: 1hr 20min
- MULTI-GRAIN PIE DOUGH (SINGLE CRUST):
- 1 1/4 cups whole wheat pastry flour
- 1/4 cup flax meal
- 2 tablespoons toasted wheat germ
- 1/4 teaspoon salt
- 3 tablespoons cold butter, cut up
- 3 tablespoons canola oil
- 3 tablespoons ice water
- 2 teaspoons olive oil
- 4 ounces crimini mushrooms, thinly sliced
- 3 large eggs
- 2 cups milk or light cream
- 1 tablespoon snipped chives
- 1/4 teaspoon salt
- 1/4 teaspoon pepper
- 1 large egg white
- 1/2 cup grated Parmesan cheese
- To make the crust: In a large bowl, stir together the flour, flax meal, wheat germ, and salt. With a pastry blender or two knives scissor fashion, cut the butter and the oil into the flour mixture until it resembles coarse crumbs.
- Gradually add the ice water, a tablespoon at a time, until you can gather the dough into a ball. Flatten into a disk and place on a sheet of floured waxed paper. Sprinkle a little more flour over it and top with another sheet of waxed paper. Refrigerate for at least 30 minutes before rolling out.
- To make the quiche: Preheat the oven to 375°F.
- On a lightly floured work surface, roll the dough out to a 12-inch round. Fit the dough into a 9-inch pie plate, pressing it into the bottom and up the side without stretching the dough. With kitchen scissors, trim the edge, leaving a 1-inch overhang. Fold the overhang under and flute with your fingers or crimp with a fork.
- In a large skillet, heat the oil over medium heat. Add the mushrooms, and cook until they are tender and no liquid remains in the pan. Let cool to room temperature.
- In a large bowl, whisk together the whole eggs, milk, chives, salt, and pepper. Lightly beat the egg white and brush over the pie shell. Sprinkle with the Parmesan. Scatter the mushrooms over the cheese.
- Gently pour the egg mixture over the cheese and mushrooms. Place on a rimmed baking sheet and bake for 35 to 40 minutes, until the top is golden brown and the filling is set. Place on a wire rack and let stand 20 minutes before cutting.
