Hmm, this caught my eye. I recently wrote down my fav. recipe for authentic Mexican [url=http://eauthenticmexicanrecipes.com/authentic-mexican-recipes/authentic-mexican-recipes-chiles-rellenos-de-queso-chile-rellenos-with-cheese-recip]chile rellenos with cheese[/url] , but from the way you describe the ones you've tried, the authentic ones might be closer to your "crispy blowfish" ones.
The authentic chile rellenos are fried, but only to remove their outer layer of skin: they remain soft, but are cooked with an egg batter and then layered with a tasty sauce, sort of like you describe--but it's definitely not cheese.
I've never tried the Californian style ones I think you're describing, but in case my mind is picturing something other than what you intended, maybe the authentic one is closer to what you're thinking of... Sorry I couldn't be of more help here :(
