Tammy, I am originally from Galesburg, IL. Have relatives that have always lived in Peoria. Do not recall the restaurant you are referring to, but here is the tenderloin sandwich recipe that I frequently use. There are more complex ones (if you want them, let me know):
PORK TENDERLOIN SANDWICHES ALA' MIDWEST STYLE4 boneless pork loin slices (1/2-inch thick), tenderized
