Shrimp & Spinach Quiche

Ingredients

• • ¾ cup white whole-wheat flour
  • ¾ cup all-purpose flour
  • ¼ teaspoon salt
  • 2 tablespoons cold butter
  • 2 tablespoons sour cream
  • 2 tablespoons extra-virgin olive oil
  • 2-3 tablespoons ice water
  • 2 teaspoons extra-virgin olive oil
  • 2 cups diced onions
  • ⅛ teaspoon salt plus ¼ teaspoon, divided
• • 2 tablespoons water
  • 1 cup finely chopped spinach
  • ¾ cup chopped cooked shrimp
  • 1 tablespoon chopped fresh oregano
  • ½ cup crumbled feta cheese
  • 4 large eggs
  • 2 large egg whites
  • ¾ cup low-fat milk
  • ¼ cup sour cream
  • ¼ teaspoon freshly ground pepper

Directions

• 1To prepare crust: Whisk whole-wheat flour and all-purpose flour with salt in a medium bowl. Cut butter into small pieces; using your fingers, quickly rub the butter into the dry ingredients until smaller but still visible.
• 2Add sour cream and oil; toss with a fork to combine with the dry ingredients. Sprinkle 2 tablespoons of ice water over the mixture. Toss with a fork until evenly moist; if the mixture seems dry, add up to 1 more tablespoon water. Knead the dough in the bowl a few times—the mixture may still be a little crumbly—then firmly press into a disk. Cover the bowl with plastic wrap and refrigerate for at least 1 hour.
• 3To prepare filling & bake quiche: Preheat oven to 375°F. Coat a 9-inch pie pan with cooking spray.
• 4Heat oil in a medium skillet over high heat. Add onions and ⅛ teaspoon salt; cook, stirring frequently, until the onions start to brown, 3 to 5 minutes. Add water, reduce heat to low and cook, stirring frequently, until the onions are golden brown and very soft, about 15 minutes. Remove from heat and let cool while you roll out the crust.
• 5Place the dough on a sheet of parchment or wax paper and roll into a 12- to 13-inch circle, dusting the top with a little flour, as needed. (If chilled more than 1 hour, let the dough stand at room temperature for 5 minutes before rolling.) Place the prepared pie pan upside down in the center of the dough. Holding one hand on top of the pan and the other hand underneath the paper, flip pan and dough over so the dough is lining the pan. Remove the paper and patch any tears in the dough. Trim the crust so it evenly overhangs the edge by about 1 inch, then tuck the edges under at the rim and crimp with your fingers or a fork.
• 6Spread the caramelized onions in the bottom of the crust. Layer spinach and shrimp on top of the onions and sprinkle with oregano. Top with cheese. Whisk eggs, egg whites, milk, sour cream, pepper and the remaining ¼ teaspoon salt in a medium bowl. Pour the mixture into the crust.
• 7Bake the quiche until puffed and firm when touched in the center, 40 to 50 minutes. Let cool on a wire rack for 15 minutes. To serve, cut into 8 pieces.

• Make Ahead Tip: Cover and refrigerate caramelized onions (Step 4) for up to 3 days.
