2 packages frozen chopped spinach, thawed
1 tbsp extra virgin olive oil
1/2 onion, finely chopped
2 green onions, thinly sliced
1/2 tsp dried oregano
1/2 tsp crushed red pepper flakes (optional)
Freshly ground black pepper
1/4 cup freshly chopped dill
1 tsp lemon zest
1 cup crumbled feta
Pinch of nutmeg (optional)
10 filo sheets, thawed if frozen
3/4 cup (1 1/2 sticks) melted butter
1. Make filling: Preheat oven to 375° and line two medium baking sheets with parchment paper. Using a clean kitchen towel, squeeze all excess moisture out of spinach. Transfer to a large bowl.
2. In a large skillet over medium heat, heat oil. Add onion and green onions and cook until softened, 5 minutes. Add garlic, oregano, red pepper flakes if using, and season with salt and pepper. Transfer mixture to bowl with spinach.
3. Add dill, lemon zest, feta, and nutmeg to bowl with spinach and stir until all ingredients are evenly mixed and season again with salt and pepper, if needed.
4. Remove filo pastry from refrigerator and cover with a lightly damp kitchen towel. Take 1 phyllo sheet and place on a clean surface. Brush all over with melted butter, then top with another sheet of filo. Brush second sheet of filo all over with butter, then slice into 6 long, evenly sized strips
