Tex-Mex is one of America's oldest regional cuisines, adapted from the home cooking of Tejanos, or people of Mexican descent living in Texas.
While "Tex-Mex" does not refer to a single dish, we wanted to include the broader cuisine on our list because it encompasses such a large swath of food, including chile con queso, nachos, tacos al carbon, enchiladas, and fajitas to name just a few.
