A Spicy Chicken Quesadilla features a warm, pliable flour tortilla folded over a generous filling of juicy, shredded or grilled chicken tossed in a fiery blend of Tex-Mex spices and hot sauce. Melted together with a gooey, gooey layer of Monterey Jack or cheddar cheese, it is toasted on a flat-top grill until the exterior is perfectly golden-brown and crisp, delivering a smoky, savory bite with a satisfying chili kick.
