Some chips can be made into dishes and served as an appetizer, side, hors d'oeuvre, etc. Some types of chip are often served in the combination plate, chips and dip. Other chips are sweet or strongly flavored or fragile. Tortilla chips can be used for chips and salsa, nachoes, bean dip, guacamole, or a layered dip containing multiple of these.
