This savory tart is a perfect appetizer or light lunch. Start by making a simple pastry crust and blind-baking it until it is golden brown. Then, sauté chopped asparagus in butter until it is tender and lightly browned. Spread a layer of goat cheese over the crust, then top with the asparagus and a sprinkle of fresh herbs. Bake until the cheese is melted and bubbly, and serve warm or at room temperature.
