We've had an interesting discussion of the prevalence of the dish "baked ziti" in the culture of Italian-Americans, predominantly in the east or northeastern U.S. http://chowhound.chow.com/topics/7228...
What is the Southern equivalent of the Italian-American standard "baked ziti," namely "so widespread a dish that you'll find it at virtually every family, church or social gathering in the South"?
I'm trying to figure out what that dish might be -- and not in terms of ingredients, but the prevalence of the dish. Originally, I was thinking of identifying the iconic "baked" dish, but I couldn't think of one single baked dish that is ubiquitous. So, I'm seeking the dish (baked or not) that is a cultural "marker" of social gatherings -- when you say to yourself, "this dish is everywhere I go" -- in the South. Maybe it is potato salad? Maybe it IS potato salad.
