I read through a bit of this thread and this sounds like Michigan Sauce to me. A couple that I know live here in San Antonio and they make it as a hot dog topping. They are from upstate NY. Apparently nobody in Michigan knows anything about it.
"Michigan Hot Dogs" are popular in Montreal and Quebec. It's basically just a spaghetti meat sauce on the hot dog.
You can get them at most fast food places or diners north of the border. Try La Belle Province or Lafleurs. They also serve it as italian poutine
