If you really want to start an argument, go to south Louisiana and ask if tomatoes should go in gumbo. Have to tell you, people will fight about that!
Not sure if some of these folks are really Southerners, or not. Southerners who don’t like: tomatoes, grits, gravy, etc? Oh, well, more for me! (But I do admit I don’t like watermelon OR the smell of magnolias, but don’t tell anybody!)
