I was snooping around for recipe on Southern Living website and I found an article about weird sandwiches of the South.

Southern food is just so scrumptious and yummy, if not always the lowest in fat and calories. They listed about 6 or 7 sandwiches and they all had lots and lots of mayonnaise. There was the tomato sandwich, the pineapple sandwich, the sweet onion sandwich...etc. About the 8th sandwich, what the heck, they just skipped all of the other ingredients and created a "Mayonnaise Sandwich."
