Breaded tenderloins are definitely an Iowa favorite, as they should be given the number of hogs in Iowa. A favorite at the Culver’s chain. Ted’s Coney Island around Des Moines make a great one.
And Iowa is home to the original ‘loose meat’ sandwich, the Maid-Rite, which has seen declining popularity.
Virtually every small town bar/restaurant has the breaded tenderloin on the menu.
I personally like the ones that are pounded very thin so they are a bit crispy.
I know others like them thicker. To each his/her own.
