Horseshoe sandwich

The horseshoe is an open-faced sandwich originating in Springfield, Illinois, United States. It consists of thick-sliced toasted bread , a hamburger patty or other choice of meat, French fries, and cheese sauce. While hamburger has become the most common meat on a horseshoe, the original meat was ham. The "horseshoe" name has been variously attributed to the horseshoe-like shape of a slice of bone-in ham, or to the horseshoe-like arrangement of potato wedges around the ham. It is not uncommon to substitute other meat for the hamburger, such as chicken or ham, or use more than one type of meat. The fries may also be substituted with tater tots, waffle fries, or other forms of fried potatoes.
