Honestly, I still don’t really know what “real” western food is.

French cuisine is the most classically famous example, but pretty much every western country has hundreds of years of it’s own extremely distinct culinary identity (ex: Germany, Spain, Italy, even the UK (despite the jokes)).

The US doesn’t exactly have it’s own unified thing but there are plenty of foods, and even a few entire genres of food, that are very closely tied to the american identity (Texmex is probably the most famous example). The most ‘stereotypically’ american food I can think of is probably hotdish which… I don’t actually recommend seeking out.
