Despite the name, Michigan hot dogs are practically unknown in Michigan. They are traditionally produced in New York State and Québec. This tasty street food staple consists of a long steamed roll and a steamed hot dog sausage in natural casing, and the whole thing is topped with a meaty sauce called Michigan sauce, chopped onions, and occasionally, yellow mustard.

The sauce is thick and chunky, typically made with tomatoes, vinegar, brown sugar, and cabbage, while the onions may be ordered with or buried (under the sauce).

According to a legend, pretzels without eggs have been invented in 610 A.D. by Italian monks, as a way for people to consume them during Lent. Word of the pretzel delicacy quickly spread to Germany, and the Germans, who adored these soft and crunchy treats, brought them to America in the 1700s.

From then on, pretzels had made their way across America and came to the streets of New York, becoming a staple food of factory workers and day laborers. Today, some claim that there is nothing better on a rainy day than a soft, steamy pretzel that is sprinkled with coarse salt and dipped in bright yellow mustard. 

Knish is Jewish soul food, a soft pillow of baked or fried dough that is usually stuffed with onions and mashed potatoes. This comfort food was brough to New York City's Lower East Manhattan and Brooklyn around 1900, when Jewish immigrants from Eastern Europe first started selling it from their street carts.

Round knishes are baked, while square knishes are typically fried. Today, these flavorful snacks are found throughout New York's shops and delis, and there isn't a bar mitzvah party that doesn't include knishes. As the dish gained popularity throughout the years, various unusual fillings started to be added to it, such as broccoli, cheddar cheese, corned beef, and sauerkraut. 

Bagel dog is a variety of a hot dog consisting of a regular or small-sized hot dog sausage wrapped in bagel dough. Visually, it is quite similar to pigs in a blanket. This street food staple is especially popular in New York City, Cincinnati, and Chicago.

Spiedie is a culinary icon of Binghamton, New York, a sandwich consisting of an Italian roll or slices of white bread that are filled with cubes of marinated chicken, pork, or lamb. The sandwich gained popularity during the 1940s, but its exact origins are still shrouded in mystery.

The name comes from the Italian word spiedo, which refers to a kitchen cooking spit. Not unusual, considering that the meat is grilled on a metal skewer before it gets placed in a sandwich. It is believed that Augustine Iacovelli, the owner of a restaurant called Augies popularized the sandwich. 

Reuben dog is an American hot dog variety that's believed to originate from New York City. In order to prepare it, split hot dog buns are topped with a hot dog sausage (often pan-fried in butter), Swiss cheese, sauerkraut, and Thousand Island dressing or Russian dressing.
