When we first began visiting Mexico in 2006 I did my best to learn "food" words first. Quite proudly one night in San Miguel de Allende I phoned in a pizza order, un grande con salchicha, correctly translating sausage.
Well......salchicha on a pizza in Mexico turned out to be hot dogs. Not crisped up or blackened or grilled or even fried....just warmish thick rounds of sliced, cheap hot dogs.
FFWD 10+ years and nowadays most MXN pizza menus include topping listing for both salchicha and another for salchicha Italiano.
All orders of pizza still come with ketchup packets 😝
