Yes. I have read about this here. Actually I don't even know what Americanized Tex Mex food is. I work in Los Angeles where it's very close to Olvera Street which is supposed to be "little Mexico" and also I live close to East Los Angeles. What exactly is Americanize Tex Mex Food? How is it different than the traditional Mexican food?
Chipotle, Taco Bell, and the like are "Americanized" Mexican. Tex-Mex is 'Texanized" Mexican. I wouldn't call Tex Mex the same as the kind of Americanized Mexican you get throughout the states.
Americanized Mexican: Tacos = soft flour or hard corn shell with meat (ground beef, chicken, sometimes pork) and toppings that usually include salsa or chopped tomatoes, shredded iceberg lettuce, shredded cheddar cheese, and sour cream. Burritos = soft flour tortilla filled with rice, meat, salsa, sometimes beans, lettuce, shredded cheddar, and sour cream. Tostadas = hard corn flat shell with meat, beans, shredded iceberg lettuce, tomatoes/salsa, shredded cheddar, and sour cream. Sometimes guacamole is added to this. Sides for all of these usually include rice and refried beans. Basically, every dish has the same ingredients (meat, beans, rice, cheddar, sour cream, salsa, usually shredded lettuce) arranged or cooked in different way.
Americanized tacos (see description above), for example, are nothing like authentic tacos (warm corn tortilla, meat, and one or two toppings such as onion and cilantro). The same can be said for many Americanized dishes versus authentic ones.
