re: Suggestions for items to cook/sell for an outdoor festival

Agree with what other posters have said about not competing with the same dish as other vendors. Looks like there will already be jambalaya and pulled pork sandwiches.

I can't speak to the profitability of the other options, but crawfish pistolettes and shrimp dishes done right are always appreciated, but seafood costs may cut down profitability. Meat pies, perhaps with some degree of creativity, might work well.
