Preheat oven to 400°F.
Use 8-9 inch pie dish or similar baking dish.
Defrost spinach in microwave. Squeeze spinach dry with your hands and roughly chop.
Stir together spinach, green onion, ricotta, feta, dill, egg, nutmeg, and salt in a bowl, set aside.
Working quickly, place 1 sheet of phyllo in baking dish, brush with oil/butter. Place another sheet of phyllo over the first, turning it slightly allowing the phyllo to hang over the edge.
Repeat with remaining sheets of phyllo turning each slightly to form a jagged star. Spread spinach mixture in center of phyllo. Fold phyllo over spinach mixture, brush with oil/butter and bake until golden and crispy, about 25 minutes. Slide the pie out of the pan, cut into wedges and serve.
