Slider (sandwich)
A slider is an American term for a steam-grilled sandwich, typically around 2 inches across, made with a bun. "Slider" is believed to have been first used to describe the onion-steamed small burgers at White Castle restaurants. The term has since been appropriated by other restaurants, usually to describe a small hamburger, but sometimes used to describe any small sandwich made with a slider roll. White Castle later trademarked the spelling variant "Slyder" and used it between 1985 and 2009.
Sliders can be served as hors d'oeuvres, snacks, or entrées.
