Seems like everything here (the church suppers, family reunion dinners, graduation parties, the Blossom Festival, etc, etc.) is either a crawdaddy boil, a fish fry, or if it has nothing to do with fish or crawdaddies, it's a bbq (even if there is no bbq actually on the premises).
There are the standards that will be at any of the above outdoor food fests: coleslaw, potato salad, biscuits, cornbread, pinto beans/blackeyed peas, pea salad, sausage balls, deviled eggs, fruit salad - usually encased in jello, some sort of greens, etc. While most of these are not exactly appetizing, there's not that much that's weird about them.
On the other hand, I've seen (and in most cases, eaten) . . . .
Not Pepsi Salad, but 7up Salad! Just like Pepsi Salad, but with 7up and lime jello!
Baconfat Cookies -
Glorified Rice - putting fruit, sugar, and whipped cream in rice does NOT make it good. It makes it bad. Really bad.
Baked "Yams"/Sweet Potatoes - ARGH! Sweet potatoes are called that for a reason! They're ALREADY sweet! They don't need marshmallows! Or orange juice! Or anything else! ARR! Stop torturing them! For the love of dog, stop!!
Deep-Fried Macaroni and Cheese -
Chow-chow - spooky and omnipresent, but damned good on your beans.
