Fajitas is a name that's widely used and recognized as a popular Mexican meal, but there are a few other terms that could also be used synonymously. One of the most commonly used alternative terms is "tacos al carbon," which refers to grilled meat served with tortillas, usually wrapped in foil. Another term that could be used is "carne asada," meaning "grilled meat," which is often seasoned with lime, garlic, and other spices. A less common term is "arrachera," which refers to a specific cut of beef used in fajitas. Ultimately, all of these terms refer to a delicious Mexican dish featuring grilled or sauteed meat, veggies, and tortillas.
