Unless you have eaten home-cooked mexican food, you haven't eaten anything but Tex-Mex or the equivalent.
I make fideos y pollo on a regular basis. That's a pasta dish.
Of course, I've lived in the culture, so Tex-mex to me is just Tex-mex. And Taco Hell is American fast food.

It’s called sopa seca. Or fideos (vermicelli). It is the first course alternative to soup in any civilized household or restaurant’s comida corrida.

To be expected in an ethnic restaurant. What people eat at home is probably pretty eclectic these days.
