A French tacos or matelas is a fast food dish which usually consists of a flour tortilla grilled and folded around a filling of French fries, cheese, and meat, among other deli ingredients.

French fries, chips, finger chips, french-fried potatoes, or simply fries are batonnet or allumette-cut deep-fried potatoes of disputed origin from Belgium or France. They are prepared by cutting potatoes into even strips, drying them, and frying them, usually in a deep fryer. Pre-cut, blanched, and frozen russet potatoes are widely used, and sometimes baked in a regular or convection oven; air fryers are small convection ovens marketed for frying potatoes.
