It seems that up until about ten years ago, every Mexican
restaurant in Texas served a side salad of just iceberg
lettuce, tomato and onion. Apparently, as a cost reduction,
that disappeared.

If green salad was served in Mexican households, was there a
dressing?

Two of the Mexican women I worked with used to serve iceberg and splash it
with white vinegar, maybe some ground up dried peppers, topped with
paper-thin lime slices with every main meal. It was delicious and different.

The Chilean national ALWAYS served iceberg and doused in straight
(fresh-squeezed) lemon juice. (That first salad was a puckering experience.)
[Damned fine cook!]

The El Salvadoran and Nicaraguan expatriates always served up some form of
citrus salad with their meals.

If that's representative, I don't think there is an "authentic" salad
anymore than there is in the US. Cooks use what's available tempered by what
they like. shrug
