Montanans know about good food. We always have. Sure, the bar has been raised quite a bit in recent years but great meats, cheeses, veggies, and bread products have always been locally available - making for some incredibly good sandwiches.
We were at dinner with some of our Scandinavian Montanan friends on Saturday night- which isn't that hard to do given the fact that there are so many Scandinavian Montanans with Minnesota ties.
I absolutely thought these things were invented in Montana. There are some foods that have such mass appeal, you're safe to order them with just about anyone. America is home to so many delicious culinary inventions, it's hard to pick one that applies as a favorite to so many.
