Turn on your oven and set it at 375°F (190°C). Clear your workspace and gather up your ingredients. If using frozen spinach, make sure it's drained and dried out.
02 -
Warm a skillet over medium heat with a drizzle of olive oil. Cook your onions and garlic until soft and aromatic. Toss in spinach and stir until wilted down. Add pepper, salt, and squeeze in the lemon juice. Keep cooking on high until any moisture vanishes completely.
03 -
Let the spinach cool in a large bowl for a bit. To it, mix in all your cheeses, chopped parsley, the beaten egg, toasted nuts, and the nutmeg. Stir everything until it's combined well.

Coat the bottom of a 9-inch pie dish or a larger rectangular baking pan with a layer of oil or butter to make sure nothing sticks.
05 -
Spread two filo sheets flat, brushing both with butter or oil. Take a few spoonfuls of your spinach mixture and layer it on top, leaving some space around the edges. Roll the coated filo into a tube, then curl it into a snail shape, starting from one edge of the pan.
06 -
Continue layering filo, spreading filling, rolling into tubes, and coiling them next to each other in the pan. Don't make the rolls too tight, or the pastry could rip. Be mindful not to overstuff them, so the spirals come out clean.
07 -
Tuck any filo edges neatly around the pan. Cover the entire surface evenly with a generous brushing of butter or olive oil to help it bake golden brown and crispy.
08 -
Put the pan in the oven and bake for 25-30 minutes. You want a perfectly crisp, golden-brown top, with the filling properly set. Let it cool slightly before slicing and serving warm.
