There's one thing I would describe food in the US as it's not bland. We show up together more different cultures foods than anywhere else on the planet... If anything, our food is a horrible abomination of overly seasoned monstrosities.
I legitimately can't think of a single place in America where what you're saying is remotely true outside of maybe like North Dakota...
Like America still holds the record for most cheese consumed per capita. Hell America's third, in the most types of cheeses consumed and produced only behind France and Italy. When it comes to cheese, America does not f*** around.
Hell this entire section's America wear insulting someone's cheese can get you a shot. We give France a run for their money when it comes to cheese snobbery. You have to be incredibly ignorant to think America doesn't care about cheese.
The only real thing that America struggles with is heat. We love spices. We love peppers. We love flavors and herbs. But just pure raw heat for heat's sake is sort of Hit or Miss.
But at the same time we also consume more hot sauce than anyone else in the world. So figure that one out.
