A collop is a slice of meat, according to one definition in the Oxford English Dictionary. In Elizabethan times, "collops" came to refer specifically to slices of bacon. Shrove Monday, also known as Collop Monday, was traditionally the last day to cook and eat meat before Ash Wednesday, which was a non-meat day in the pre-Lenten season also known as Shrovetide. A traditional breakfast dish was collops of bacon topped with a fried egg.
