A thin, round piece of food, such as a hamburger patty or a peppermint patty. Recipe: Salmon Patties
Patty is a character in the comic strip Peanuts, created by Charles M. Schulz (not to be confused with Peppermint Patty, a different and later character from the same strip). Her closest friend is Violet.
A patty is a disc-shaped serving of meat or meat substitutes. The meat is ground and then packed and re-shaped to form round discs, cooked (if applicable) and eaten. They can be eaten a la carte, as a Salisbury steak, or in a hamburger.
