What is the definition of horderves?

Answer:

Hors d'oeuvres are like small snacks before a big meal. Usually they are finger foods brought around by waiters at a fancy event, and sometimes they are small plates served before the main meal. Anything can be an hors d'oeuvre. They are defined by the size and quantity.

Common hors d'oeuvres are things like miniature quiches, or tasty fillings inside puff pastry, or chicken wings, pigs in blankets, cheese and crackers, or crudites (vegetable sticks).
