This savory tart is perfect for a fancy brunch or dinner party. Preheat your oven to 375°F. Roll out a sheet of puff pastry and place it in a tart pan. Prick the bottom with a fork and bake for 10 minutes. In a bowl, mix together grated Gruyere cheese, chopped asparagus, chopped fresh herbs, and beaten eggs. Pour the mixture into the partially baked crust and bake for an additional 20-25 minutes, or until the filling is set and the crust is golden brown. Serve warm or at room temperature.
