The name bruschetta comes from the Italian verb bruscare meaning āto toastā. Crostini means ālittle crustsā. Both are generic terms to describe a toasted, grilled or fried bread with a savoury topping. Either can be served hot or cold.

In Spain we call them tostadaās and they are indeed an ideal way to start the day. Light and easy, typically with cheese and tomato but easily made into more of an elaborate dish with goats cheese and peppers (as shown here).
A favourite is tostada with butter separate and marmalade. Tostada con mantequilla con marmalade seperado.
