Maxwell Street Polish
A Maxwell Street Polish consists of a grilled or fried length of Polish sausage topped with grilled onions and yellow mustard and optional pickled whole, green sport peppers, served on a bun. The sandwich traces its origins to Chicago's Maxwell Street market, and has been called one of "the classic foods synonymous with Chicago". This sandwich is widely said[by whom?] to have been created by Jimmy Stefanovic,[citation needed] a Macedonian immigrant who took over his aunt and uncle's hot dog stand in 1939 located at Maxwell and Halsted in Chicago's old Maxwell Street market district. The Express Grill, which is located right next door to Jim's, advertises itself as the "Original Maxwell St. Polish" on its marquee, although it arrived after Jim's and serves almost an identical menu. Due to their virtually undivided storefronts and 24-hour service at the original Halsted Street location of both stands, Jim's Original and Express Grill had an added element of confusion for the casual observer not attentive to the change in signage a matter of feet in distance. Despite the competition, the Maxwell Polish sausage sandwich soon grew to be one of Chicago's most popular local offerings, along with the Chicago-style hot dog and the Italian beef sandwich. Due to the University of Illinois Chicago's South Campus development the Maxwell Street market district was razed and the two stands moved in 2005. After decades of coexisting at the intersection of Halsted and Maxwell Streets, the two have relocated their side-by-side competition a half block east onto Union Avenue, adjacent to the Dan Ryan Expressway on-ramp at Roosevelt Road.
