Spanakopita is a classic Greek dish made with phyllo dough, spinach, and feta cheese. The phyllo dough is layered with a mixture of sautéed spinach, onions, garlic, and herbs, then topped with crumbled feta cheese. The layers of phyllo dough become crispy and golden when baked, while the filling remains moist and flavorful. Spanakopita can be served as an appetizer or a main dish, and it is perfect for entertaining or a family meal.
