This famous regional dish is a type of salad that originated in western Pennsylvania. Basically it is a house salad with chicken and topped off with crispy french fries! The fries make a delicious addition instead of traditional croutons. The addition of fries to the Pittsburgh salad is a tasty twist that's said to be a nod to Pittsburgh's love of french fries, which are commonly served sandwiches and as a side dish with meals in the city of Pittsburgh.
