Fajitas are some of the most popular dishes on a Mexican restaurant menu, and they've also found their way onto the menus of grilles and taverns. The delicious dishes are served with marinated meat, grilled onions and peppers, and wrapped in a tortilla, and are often served with additional garnishes and toppings, including guacamole and sour cream.
The Tex-Mex dish has a day devoted to its deliciousness—National Fajita Day, which falls on August 18.
