Queso is the Spanish word for cheese but (in the US) it is often used to refer to a cheese-based dip or sauce for tortilla chips.
When I google "what is queso?", Google says "short for chile con queso". Looking it up on Wikipedia leads to a disambiguation page where the page for Chile con Queso looks like the relevant result. That page says chile con queso is "sometimes described simply as queso".
However I'm also finding a lot of people who think that it is just a cheese sauce that doesn't have anything to do with chile.
So is queso short for chile con queso or are they distinct dishes?
