AdvancePierre introduces the BIG AZ Angus Cheddar Cheeseburger, an extension to its BIG AZ line. The BIG AZ Angus Cheddar Cheeseburger features an over-sized charbroiled Angus beef patty with fresh, off-the-grill flavor sandwiched between two slices of cheddar cheese and served on a hearth-baked BIG AZ bun. The BIG AZ Angus Cheddar Cheeseburger will be available in June 2014. Sandwiches have a 14-day refrigerated, 12-month frozen, shelf life. Hand-wrapped BIG AZ sandwiches can hold hot in a sandwich warmer for up to four hours.
