Crostini means "little toasts" in Italian. It is a small slice of grilled or toasted bread intended to be eaten with toppings like cheeses, meats, spreads, bruschetta or a tapenade. And why buy crostini when you can easily make your own? They are so much better fresh, and perfect for an appetizer with Bruschetta, Three-Olive Tapenade, or your favorite spread.
