Fried rattlesnake with smashed potatoes (potatoes wrapped in foil and baked in the coals then smashed) and Dutch oven biscuits with milk cream gravy. This would certainly win a scouting cooking contest ... but the prep work could be a problem - especially catching, skinning and gutting the little critters!
Some less dangerous options:
1 - Shrimp and okra gumbo served over rice (you can get pre-made dark roux in a jar) and to kick up the flavor you can make a stock from the shells from the shrimp - otherwise use chicken stock, not water like most recipes call for.
2 - Shrimp Creole served over pasta (angel hair, spaghetti, fettuccine, or linguine) - or rice.
3 - Crawfish Etouffee served over rice - if you can find fresh or frozen crawfish tails.
4 - Smoked sausage Jambalaya
You could also go with ...
Pork pot roast with a packaged onion or mushroom gravy with baked sweet potatoes and DO cornbread.
Braised country style pork ribs with sweet-n-sour red cabbage, onions and apples.
Chicken-fried steak with smashed potatoes and gravy ...
Oh - and a DO peach cobbler for dessert!
This doesn't include the obvious beef pot roast with onions, carrots and potatoes; beef stew, chili, slum gullion, fried/grilled on a stick catfish, etc.
I know that all of these can be cooked over a campfire .... I did it when I was a kid in scouts.
