Active Time: 35 minutes
Total Time: 1 hour 20 minutes, plus chilling and cooling
Makes 6 main-dish servings
3/4 cup all-purpose flour
1/2 cup whole wheat flour
salt and pepper
4 tbsp cold trans-fat free margarine, cut up
1/4 cup low-fat buttermilk
3 large egg whites
1 leek (6 to 8 oz) white and light green parts only, cut into thin half-moons
1/2 tsp chopped fresh thyme leaves
6 oz baby spinach (about 6 cups)
2 large eggs
1 1/3 cup reduced-fat (2%) milk
1/4 cup freshly grated Parmesan cheese
1 tsp Dijon mustard
1 oz. goat cheese, softened
Preheat oven to 400. In food processor, pulse fours and 1/4 tsp salt until combined. Add margarine; pulse until coarse crumbs form. Add buttermilk; pulse until just blended. If dough does not stay together when pinched, add ice water, 1 tbsp at a time, pulsing after each addition. Shape into disk. Wrap in plastic wrap; refrigerate 20 minutes or overnight. (If chilled overnight, let stand 30 minutes at room temperature before rolling.)
Spray 9-inch glass pie plate with cooking spray. On lightly floured surface, with floured rolling pin, roll dough into 12-inch round; place in pie plate. Gently press against bottom and up side without stretching; trim edge. Prick holes in crust with fork. Line with foil; fill with pie weights or dried beans. Bake 15 minutes or until beginning to set. Remove 1 tbsp egg white from rest of whites; set remaining aside. Remove foil with weights; brush bottom of crust with tbsp white. Bake 5 to 6 minutes or until golden brown and dry to the touch. Cool completely on wire rack.
Meanwhile, coat 12-inch skillet with cooking spray; heat on medium. Add leek, thyme, and 1/8 tsp salt. Cook 3 to 4 minutes or until soft, stirring occasionally. Add spinach; cook 5 minutes or until mixture is very soft and dry, stirring frequently. Let cool.
In large bowl, whisk whole eggs, milk, and remaining egg whites. Stir in Parmesan, mustard, leek mixture, and 1/4 tsp pepper. Spread bottom of crust with goat cheese; place in jelly-roll pan. With strips of foil, cover crust edges to prevent overbrowning. Pour egg mixture into crust; bake 32 to 35 minutes or until knife inserted in center comes out clean. Cool on wire rack 15 minutes to serve.
