I like to pre-cook Chili and bring it in a big plastic bag in the cooler. Just heat and add fritos and shredded cheese.
Foil dinners- I would look up how to make these because mine never come out flavorful enough but you put a chicken breast or chicken tenders on top of foil, add veggies, potatoes, herbs, a little chicken broth poured on, wrap it up, then put the foil packets on the camp grill to cook.
You can make pizzas over a camp grill
Make a morning fire- wrap pilsbury buscuits or crescent rolls around the end of a wooden dowel or clean broomstick, cook over fire. fill the hole with jelly, butter, cinnamon, or a sausage you cooked over the fire too.
My other fun breakfast fave= boil in a bag individual omelettes. Have a large pot of boiling water on the camp stove. Crack an egg into a heavier plastic sandwich bag and squish it around to scramble it. Add cheese, ham, whatever pre-chopped omelette add-ins you want to have available. Then you hold your bag in the boiling water with tongs until it is cooked in there and slide it out onto your plate. Just don't let the plastic bag touch the sides of the hot pot or it can melt the bag.
The key is always prep- try to bring everything chopped and bagged and ready to go :) We do extended camping (like a week plus) with our in-laws and my MIL sets up a whole kitchen and we all eat as good if not better than the rest of the year. But when it's just me and hubs we go for simple and advanced prep.
