Those brats that come with the cheese already inside them are a complete racket because if you cook them properly you cook the cheese right out and then where are you? Sans cheese is where. Dispossessed of the "added value" cheese you purchased. Having been, as the venerable brat ancients used to say, uncheesed.
Oh man, this touches on an important funfact that not everyone might know: #Johnsonville, the meat company based in Johnsonville, WI, and famous for their voluminous bratwurst and bratwurst-adjacent products, bankrolls Wisconsin fascists, the ones that gerrymandered the shit out of the state and think laws and basic common decency should not apply to them. Johnsonville is white-dogshit-grade awful people and you shouldn't buy their products. Look for Klements or Usingers, both MKE-based and profoundly less shitty companies, cuz you'd almost HAVE to be haha.
