A mushroom and cheese phyllo tart is a delicious vegetarian dinner option. The phyllo pastry is layered with a mixture of sautéed mushrooms, onions, and garlic, then topped with a generous amount of cheese. The tart is baked until the phyllo pastry is crispy and the cheese is melted and bubbly. This dish is perfect for mushroom lovers and can be served as a main course or as an appetizer.
