First, fajita is a Tex/Mex dish created in the American southwest, not Mexico. It is made from strips of grilled meat with cooked bell peppers (green, orange, yellow, red, or a combination), and onions, and can be piled into either a soft corn, or flour tortilla. Originally, it was made with skirt steak, but now includes chicken, turkey, even fish. Unlike tacos, and burritos, the fillings are placed on top of the tortilla, or to the side, It is not assembled. You get to do that, and put any condiments you want onto it, such as pepper sauce, guacamole, shredded cheese, etc.
I rarely order fajitas. Instead, I opt for tacos in a lightly fried soft corn tortilla, with either shredded beef, or carne asada. I like having refried beans on the side, with diced tomato, diced cucumber, shredded lettuce, and grated cheese, all dressed with Tabasco, Sriracha, and sour cream.
If I'm in the mood for a flour tortilla, I get either a wet burrito, an enchilada, or burrito supreme, again with carne asada, cilantro, refried beans, shredded cheese, guacamole, and spicy sauce. I don't want rice in my burrito.
If I'm yearning for a strong masa flavor, the i order tamales.
To me, fajitas are both boring, and messy to eat. Just MHO.
