This savory tart is made with a mixture of mushrooms, goat cheese, and herbs. The puff pastry is flaky and buttery, while the filling is creamy and flavorful. This tart is perfect as an appetizer or a light lunch. To make it, simply sauté some mushrooms with garlic and onion, mix it with crumbled goat cheese, herbs, and a beaten egg. Roll out the puff pastry, place it in a tart pan, fill it with the mushroom mixture, and bake until golden brown and crispy.
