Trivia: The BLAT variation of the BLT sandwich adds what ingredient?
Correct Answer: Avocado
So why is this answer correct? : The BLT — bacon, lettuce, and tomato — is the quintessential American sandwich. In recent years, the sandwich has morphed into a BLAT with the addition of avocado. Some food historians think the original sandwich’s name may have been inspired by famous “Chicago Tribune” journalist Bert L. Taylor, who signed his “A Line o’ Type or Two” column “B.L.T.”
