2 tsp. olive oil
3 cups chopped onion
1 tsp. sugar
1/2 tsp. salt
2 cups frozen Southern-style hash brown potatoes, thawed
1 (11-oz.) can refrigerated soft breadstick dough
Cooking spray
1 (10-oz.) package frozen chopped spinach, thawed, drained, and squeezed dry
1 cup fat-free milk
3 large egg whites
2 large eggs
1-1/4 cups (5-oz.) crumbled feta cheese

To decrease fat, we’ve used 2 egg yolks and 5 egg whites. Some egg yolks are necessary to produce a creamy filling. You can refrigerate the leftover yolks for up to 3 days in an airtight container (add a tablespoon of water so the yolks don’t develop a film).
Preheat oven to 350 degrees.
Heat olive oil in a large nonstick skillet over medium heat. Add onion, sugar, and salt; cook for 30 minutes or until golden brown, stirring occasionally. Stir in potatoes and cook for 5 minutes or until lightly browned. Remove from heat.
Unroll dough, separating into strips. Working on a flat surface, coil one strip of dough around itself in a spiral pattern. Add second strip of dough to the end of the first strip, pinching ends together to seal; continue coiling the dough. Repeat procedure with the remaining dough strips. Cover and let dough rest for 10 minutes. Roll dough into a 12″ circle, and fit into a 10-inch deep-dish pie plate coated with cooking spray.
Spread potato mixture in bottom of prepared crust, and top with spinach. Combine milk, egg whites, eggs, and cheese; pour the milk mixture over the spinach. Bake at 350 degrees for 1 hour or until set, shielding crust with foil after 50 minutes. Let stand 10 minutes before serving.
