Greek Onion and Squash Pie

Oven375°F (190°C or gas mark 5)

Time40 to 45 minutes

Ingredients

olive oil cooking spray
1 x 8-ounce (240 g) onion, chopped
½ pound (240 g) zucchini, grated
½ pound (240 g) summer squash, grated
3 ounces (80 ml) liquid egg substitute
⅓ cup crumbled low-fat feta cheese, about 1 ounce (30 g)
1 tablespoon (9 g) all-purpose flour
3 tablespoons 30 g) chopped fresh oregano or 1 tablespoon (15 ml) crushed dried
8 sheets phyllo dough

Directions

Prepare the filling

Preheat oven to 375°F (190°C or gas mark 5).
Lightly coat a non-stick skillet with cooking spray.
Place over medium heat and add the onion and two squashes.
Cook, stirring occasionally, until vegetables are soft and all liquid has evaporated, about 8 to 10 minutes.
Place the vegetables in a bowl to cool slightly.
Add the egg substitute, feta cheese, flour, and oregano, then stir to combine and set aside.

Assemble the pie

Place a sheet of phyllo dough on a 9-inch (22.5 cm) pie plate, allowing any excess dough to loosely drape over the sides, and lightly coat with cooking spray.
Repeat, using three more phyllo sheets, spraying after each addition.
Pour the prepared vegetable-egg mixture into the pie shell and smooth out the surface.
Top the pie with the remaining four sheets of phyllo, spraying each layer with cooking spray before adding another sheet.
Cut the phyllo 1 inch (2.5 cm) beyond the rim of the pie pan.
Fold this dough over towards the center to make an edge just inside the rim.

Bake and cool

Bake for 40 to 45 minutes, until nicely browned and puffed.
Allow to cool to room temperature before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Zucchini: Forms the bulk of the filling; cooking off its liquid keeps the pie from turning soggy.
Liquid egg substitute: Binds the vegetables and sets into a sliceable, custard-like filling when baked.
Feta cheese: Adds salty, tangy flavor and a crumbly richness to the filling.
All-purpose flour: Absorbs residual moisture and helps the filling hold together when baked.
Oregano: Provides the dominant herbal aroma that defines the flavor of the pie.
Phyllo dough: Bakes into crisp, golden, flaky layers that encase the filling.

The step that matters

Cook the squash until all liquid has evaporated. Water left in the vegetables would thin the egg mixture and steam the phyllo from below, leaving a soggy base instead of a firm, browned pie.
