Grouper Sandwiches

Grouper is available year-round, but it's best known as a wintertime fish. Back in the day, before refrigeration was common, grouper was so plentiful during the colder months that fisherman would put them in ice to keep them fresh until they returned to port. Since then, the name stuck and grouper has been a popular dinner fish.
