When I car camp, I always bring a cast iron Dutch oven. Nachos are simple and popular. Pre-cook meat beforehand. Chips. Bag of shredded cheese. Can of pre-cut olives and jalapenos. Just melt the cheese.

I make those cans of cinnamon rolls for breakfast in the Dutch. Cobblers work well for dessert.

Most popular dinner is pulled pork sandwiches. Put a pork butt roast or loin in the crock pot at home with a can of (not diet) root beer. Cook 8-10 hours on low until it pulls apart with forks. Dump the root beer. Pull the pork and add barbecue sauce. Let cool and put the whole thing in a gallon Ziploc bag. Reheat in camp and serve on buns with coleslaw.
