The traditional food 

American cuisine has been influenced by Europeans and Native Americans in its early history. Today, there are a number of foods that are commonly identified as American, such as hamburgers, hot dogs, potato chips, macaroni and cheese, and meat loaf. "As American as apple pie" has come to mean something that is authentically American.

There are also styles of cooking and types of foods that are specific to a region. Southern-style cooking is often called "American comfort food" and includes dishes such as fried chicken, collard greens, black-eyed peas and corn bread. Tex-Mex, popular in Texas and the Southwest, is a blend of Spanish and Mexican cooking styles and includes items such as chili and burritos and relies heavily on shredded cheese and beans.

Jerky, dried meats that are served as snacks, is also a food that was created in the United States, according to NPR.
