Greens and Feta Pie

In large bowl, whisk together flour, salt and baking powder. In separate bowl, whisk together oil, milk and egg; pour over dry ingredients. Using wooden spoon, stir to form fairly smooth dough.

Turn out onto lightly floured surface; knead until smooth, about 2 minutes. Press into disc; wrap in plastic wrap and refrigerate for 30 minutes. (Dough will seem oily when removed from refrigerator.)

Filling: Meanwhile, in skillet, heat oil over medium heat; cook onion and leek, stirring occasionally, until softened, about 5 minutes. Transfer to large bowl.

Wash spinach and beet greens in several changes of water; drain. In batches, place spinach and greens in large pot with just the water clinging to leaves; cover and cook over medium-high heat, stirring once, until wilted, 3 minutes. Let cool.

Transfer to sieve; squeeze out moisture. Add to onion mixture along with feta and mozzarella cheeses, eggs, dill, salt and pepper; mix well. Set aside.

On floured surface, roll out dough to 16-inch (40 cm) circle. Loosely roll around rolling pin; unroll onto 9-inch (23 cm) cast-iron skillet or metal baking dish, letting dough hang over edge. Mound filling in centre; lift pastry up over filling, letting pastry fall naturally into folds and leaving 5-inch (12 cm) opening in centre.

Bake in bottom third of 375°F (190°C) oven until pastry is golden and filling is steaming, 45 minutes. Let cool for 30 minutes. Refrigerate until cold. Cover and refrigerate for up to 24 hours. Cut into wedges.
