I tried that once. Potato salad down the middle of a large shallow bowl with chicken sausage gumbo on one side and seafood gumbo on the other. It was good, but the potato salad made the gumbo cool off too quickly. If you like it spicy, try this. http://www.foodnetwork.com/recipes/bobby-flay/mesa-grills-southwestern-potato-salad-recipe.html
It's the cool off shit people like. My family used to do PS in gumbo for the lil kids. Glad I outgrew that shit. Plus they were way north I-10. Almost to Ville Platte, Prairies.
