I’m from South Dakota where we would have a casserole (Or do you call it a hot dish??? There must be a map of the preferred term…) at least once a week. Growing up, our style was basically combine whatever you have left in the fridge that needs to be eaten, some type of rice/pasta, ground beef (usually), mix in some spices, throw some cheese on top, and bake it for a bit. Voila! Lunch/dinner/supper (whatever you call it…probably a map out there somewhere of this, too) was served!
