I take internet surveys with a grain of salt, but Google is pretty good at tracking searches and their originating locations. Still, this is pretty hard to believe.  In an article from Delish, they tracked the most popular searches for Super Bowl Party foods by state and Montana's was... Lentil Soup?

Never in my life have I been to any party where I was offered lentil soup, much less an event that centered around sports.  My only guess is that this has to be coming from Bozeman and Missoula folks.  I've never attended a party in either of those cities, but I guess they're full of craft beers and healthy tailgate snacks.
