Hors d'oeuvres are small food items served before the main courses of a meal. The term is French and means "outside the works." Eating small portions before a main meal has been practiced for centuries in cultures around the world. Common hors d'oeuvres include olives, cured meats, cheeses, vegetables and more. When serving hors d'oeuvres, it is recommended to provide 5-7 portions per person for appetizers before a meal and 10-12 portions for finger foods at parties. Buffets or servers passing hors d'oeuvres are good ways to present them so guests can socialize while selecting food.
