Beside from the obvious roasted hot dog.

Roasted open fire hot dogs kick ass. Make sure to put them lengthwise on the stick, not widthwise.

Sandwiches (make/buy before you go)

for breakfast l fill plastic baggies full of my cereal of choice and when l am hungry l just fill with milk from the ice chest. l make them before l go so its an instant meal with little clean up involved.

l am shocked that nobody has said the obvious: Hobos

You cut up some potatoes (this can be done before you leave as long as you keep them in cool water); add some celery and carrots - maybe green beans. Add whatever you feel would taste nice. Mix this with cube steak and a hunk of better.

Wrap it in aluminum foil and place on the edge of the fire to cook for 45 minutes to an hour.

Enjoy.

You can approach this from several angles. You already know about hotdogs & s'mores, right? And hamburgers, l am sure. But if u want something a little classier, then u gotta plan ahead & bring along some utensils other than a sharp stick to poke through the hotdogs. What a lot of folks do is bring a cookpot & pre-packaged freeze-dried meals they purchase at an outdoors store like Bass Pro or Gander Mountain.you can even order 'em online from Cabela is sporting goods catalog.
Or u can haul picnic coolers with the fixin is to prepare a variety of sandwiches using ground ham, cold cuts, bread & mayonnaise, ( l prefer to bring stuffed pita pockets).heck, use ur imagination!

May l suggest a meal, that is not tough, but will make u camp hero? LOTS of aluminum foil. Fresh fish fillets. Potatos. Onion. Salt & pepper. Lay out 18'' foil. Layer 1'' chunks of potato on foil. Lay a couple fillets on potatos. Put a few slices of onion on fish. Salt & pepper. Wrap tightly, anf lay by fire for about 20 min- depending on fire. Done when potato is soft. No need to peel the spuds. Eat dinner right out of the foil. Fit for a king. Fresh lemon is great here. This sounds liker a lot of work, but really takes about 20 minutes prep. l must make clear, these r like camp tv dinners. Each person gets their own foil bundle- each bundle a meal.
