St. Paul Sandwich

St. Paul sandwich is an American sandwich originating from St. Louis, despite its misleading name. Typically sold in Chinese restaurants in the city, the sandwich consists of tomatoes, pickles, mayonnaise, lettuce, and an egg foo yung patty sandwiched between two slices of white bread. Its key ingredient, egg foo yung is a combination of an overcooked/fried omelet and fillers such as meat, shrimps, or bean sprouts. St. Paul sandwich is traditionally served on wax paper and enjoyed freshly prepared.
