Warm up the oven to 375°F (190°C). If you're using frozen spinach, defrost it and squeeze out the extra water.

In a frying pan on medium heat, add some olive oil. Toss in the onion pieces and garlic. Cook until soft and clear. Mix in the spinach, pepper, and salt. Wilt the greens, pour in the lemon juice, and cook on high heat till the liquids dry out.

Move the sautéed spinach into a big mixing bowl. Let it cool a bit. Throw in the cheeses, egg, parsley, toasted pine nuts, nutmeg, salt, and pepper. Stir well so it's all evenly combined.

Use olive oil to coat the base of a 9-inch pie dish or a 9x13-inch baking pan.

Lay two sheets of filo pastry flat. Brush them generously with melted butter. Scoop out 4 tablespoons of the spinach mix and spread it on the pastry, leaving a 2-inch edge. Roll it up loosely into a log, then shape it like a coil in the pan. Repeat until the dish is loaded.

Coat the whole surface of the arranged pastry with olive oil. This makes it crispy and golden later.

Pop it into the preheated oven and bake for 25-30 minutes till the surface is nicely golden. Take it out and let it cool a little. Cut into squares or triangles to serve.
