Roast pork sandwiches are a staple of numerous sandwich shops throughout Philadelphia. The bread roll is typically topped with sesame seeds and loaded with a generous spoonful of pork juices. It is then stuffed with either sliced pork roast, roast pork chunks, or pulled pork, along with broccoli rabe (or spinach), and melted cheese such as provolone.

The condiments are optional and every customer can choose some of them according to personal preferences. These succulent sandwiches are popular in Philadelphia due to their simplicity and a nice balance of flavors.

The Philadelphian icon known as Philly cheesesteak is an extremely popular sandwich consisting of thinly sliced pieces of steak and tender, melting cheese in a long and crusty hoagie roll. It was invented in the 1930s in what is now a Philadelphian institution called Pat's King of Steaks.

Pat's started as a regular hot dog stand in South Philadelphia, and one day Pat had decided to make himself a sandwich consisting of thinly sliced rib-eye steak and cooked onions placed into an Italian roll. When a hungry cab driver stopped by and smelled the beef, he forgot about the hot dogs, and Philly steak sandwich was born. 

Submarine sandwich consists of a long, split bread roll, filled with numerous ingredients such as meats, cheeses, sauces, vegetables, and seasonings. Depending on the regional variety, the sandwich is called differently throughout the United States.

In the Midwest and California, it's grinder, in New York and Northern New Jersey, it's hero, in Delaware, it's sub, and in Baltimore, South Jersey, and Philadelphia, it's called a hoagie. Around New Orleans, it's known as po'boy, and in Maine, it's Italian sandwich, even if it has nothing to do with Italy. 

Hoagie has been declared the official sandwich of Philadelphia in 1992, consisting of an Italian roll that is sprinkled with oil and vinegar, then layered with onions, tomatoes, shredded lettuce, provolone cheese, and different types of meat according to the customer's preference.

The authentic Philly hoagie is complete only after the addition of oregano, basil, salt, and pepper. Pickles and mayonnaise are strictly forbidden. There are many theories about its origin, but the one that sounds most likely involves a jazz musician turned sandwich shop owner called Al De Palma. 

Along with Banana Split, sundae is one of the most served ice cream-based desserts in the United States of America. A sundae is ice cream topped with a sauce or syrup, typically served in a bowl. The most popular varieties of sundae are chocolate caramel, butterscotch, and strawberry.

Cherries, dairy cream, and nuts are the most common additions to the popular treat. Food historians still argue about the origin of the ice cream sundae, but there are three theories which remain the most popular. The first one says it was created in Illinois, where the law prohibited the selling of soda water on a Sunday. 

Although archaeologists had found some petrified remains of fried cakes with holes in the center, it is still unclear how could the early Native Americans prepare these delicious fried dough desserts that we know today as doughnuts. In the past, doughnuts were known as olykoeks (oily cakes), and the pilgrims from Holland are credited for bringing them to the United States.

Those early doughnuts were often made with prunes, raisins, or apples in the middle. During World War I, the doughnut was already an American favorite, consumed by soldiers that were fighting overseas as a reminder of home. In the 1950s and the 1960s, the popularity of these treats was so big that new doughnut chains started appearing on the market, such as Krispy Kreme and Dunkin' Donuts, helping in the perception of doughnuts as breakfast food. 

An ice cream float is a beverage consisting of ice cream that is placed in a soft, fizzy drink. One of the most popular varieties of the beverage is a root beer float. The origins of ice cream floats date back to the 19th century. It was invented in Philadelphia by Robert Green, a soda shop operator who ran out of cream and decided to use ice cream instead of it.

Shortly after, his daily earnings soared from $6 to $600. With the popularity of ice cream floats, it is no wonder that there are numerous variations such as chocolate ice cream soda, coke floats, purple cow, butterbeer, and Boston cooler. 

Despite its name, whoopie pie is actually an enlarged cookie sandwich consisting of two soft chocolate cake cookies with a sweet and fluffy white filling sandwiched in between. It is believed that whoopie pie has a Pennsylvania Amish origin, although today it is extremely popular throughout New England, especially in Maine.

According to the Amish, when children would find this sweet treat in their lunch bags, they used to shout “Whoopie!“, hence the name.

Somewhat similar to a calzone, the American stromboli is a savory type of turnover filled with classic pizza ingredients: mozzarella or other types of cheese, Italian meats like salami, pepperoni, bresaola, and capocollo, and sometimes even vegetables, while the marinara sauce is served on the side, rather than baked inside with the filling.

The dough can be either Italian bread dough or standard pizza dough, and before baking, the finished product is rolled into a loaf, similar to that of a jellyroll. Unlike calzone, stromboli did not originate from Italy, but supposedly from suburban Philadelphia where it was invented in the 1950s and named after one of Roberto Rossellini's movies.
