Fajitas trace their delicious roots to the Rio Grande Valley of Texas and northern Mexico, where vaqueros (cowboys) historically grilled less desirable cuts of meat over open campfires, serving them with warm tortillas. The sizzling, smoky essence of that tradition has evolved into a beloved Tex-Mex staple. This foil packet adaptation borrows a brilliant technique from classic outdoor cooking and French en papillote methods. By sealing the marinated chicken and vibrant vegetables inside heavy-duty foil, you trap the steam and juices, mimicking the effect of a screaming-hot cast-iron skillet while locking in every drop of flavor. Whether you're cooking in the oven, firing up the grill, or sitting around a campfire, this method delivers a portable, mess-free fiesta.
