01 - Preheat the oven to 350°F. Lightly grease a 9-inch round or square baking dish.
02 - Heat 1 tablespoon olive oil in a large skillet over medium heat. Add spring onions and cook until softened, approximately 2 to 3 minutes.
03 - Add spinach in batches, stirring until wilted and excess moisture evaporates. Remove from heat and allow to cool. Squeeze out residual liquid and chop coarsely.
04 - In a large bowl, combine the cooled spinach mixture with dill, parsley, crumbled feta, ricotta, eggs, nutmeg, salt, and pepper. Mix until well incorporated.
05 - Place one sheet of filo in the prepared dish, allowing edges to overhang. Lightly brush with melted butter. Repeat with three more sheets, brushing each and alternating directions for even coverage.
06 - Spread the spinach and cheese mixture evenly over the buttered filo base.
07 - Layer the remaining four sheets of filo over the filling, brushing each with melted butter. Fold overhanging edges inward to seal and brush the top sheet generously with butter.
08 - Using a sharp knife, lightly score the top layer into 6 portions to facilitate serving.
09 - Bake for 35 to 40 minutes until the pastry is golden and crisp. Remove from oven and allow to rest for 10 minutes before slicing and serving.
