Chopped cheese.
It's a relatively unknown food item in parts of the city. However, this sandwich has been a staple of the diets of students living in Jamaica, Harlem and the Bronx. The sandwich can be considered a New York Cheesesteak, featuring ground beef and onions topped with melted cheese and served with lettuce and tomatoes with mayo and/or ketchup on a hero roll. Blue Sky Deli a.k.a. Hajji's (owner of a 4-star rating on Yelp) in East Harlem is an iconic destination to pick up this sandwich for a mere $4.50.
The sandwich, a quick and cheap lunch option, has drawn criticism when restaurants outside of the slums featured it on their menu. Whole Foods Columbus Circle was in hot water when it offered the sandwich for sale for $8 in 2016. White Gold, an Upper East Side restaurant, also offers chopped cheese at an $11 price tag. Many New Yorkers accused both places of gentrifying the bodega-style sandwich.
There are merits to both sides of the argument. A restaurant should have the right to add whatever they'd like to the menu and pay homage to comfort foods. At the same time, to call it a chopped cheese can be seen as very insulting. On a slightly off topic---could someone tell me which pizzeria sells the best dollar slice?
