Tomato sandwich
A tomato sandwich is a dish closely associated with the cuisine of the Southern United States. Recipes typically call for ripe-to-overripe non-commercially grown tomatoes, mayonnaise, salt, and pepper on soft commercial white bread. It is generally expected to be messy to eat. According to Tasting Table, the Virginia Chronicle is "widely credited" with the first mention of the sandwich in 1911. According to Gwinnett Magazine, the Chronicle reported a man describing his lunch as "a tomato sandwich, a slice of watermelon, iced tea, and a slice of coconut cream pie". The tomato sandwich is associated with Southern cuisine and according to Yahoo News is considered an important part of that cuisine. According to Chuck Reece, editor of Georgia Public Radio's Salvation South, the tomato sandwich is "one thing—one perfect thing—about which every Southerner can agree". The New York Times called it "the sandwich southerners wait for all year". Jenn Rice, writing in Garden & Gun, says "The taste of tomato slathered in mayo is such a part of our summer memories that it’s practically part of our DNA."
