I'm sure there are plenty of basic white people in Middle America who make plain chicken and shyt like that. But traditional Southern food (especially Cajun) is very good, even among cacs. The Northeast is filled with Italian-Americans and other spicy cacs like Greeks.
As far as Europe goes, Southern European food in general is good, as well as French food. British Isles traditional cuisine might be nothing special, but curry is very popular there and the restaurant scene has gotten pretty good. So even those pasty ass Brits appreciate rich flavors.
I'm not too familiar with Eastern European food but I did have a Hungarian beef stew the other day and it was heavily seasoned.
Northern European food is probably trash but those countries have small populations and haven't made a huge mark on the Americas.
