This came up in my taco feed.
British tacos!
Tacos with carrots and celery?
That’s pretty funny. Love that they call tortillas “tacos”. And “roll your own”.
Sam from Not Not Tacos has made a go off very non traditional tacos in the heart of San Diego’s food mall. Check out the menu.
Soft tacos are A Thing, and they can “authentically” be filled with all sorts of stuff, so that part’s fair enough (though calling plain tortillas “tacos” in the ingredients list looks a little odd, like calling hamburger buns  “hamburgers”). And while the filling doesn’t seem very Mexican (or Tex/Cal/etc-Mex), it does looks like a halfway decent start to ropa vieja. So allowing for a little mixing-up of Latin American cuisines, it’s a lot less odd than some of the other things I’ve seen done to “foreign” food by various cultures (and by no means just Western cultures…)
