Refried beans are a favorite, or eggs for breakfast. I don't really ever cook by recipe when camping (nor at home). We used to have a coleman grill/griddle with a 3rd burner that was great for veggie burgers and sausage, but all that stuff is wheat and I can't eat it anymore. Now most of the meals are single burner skillet meals, although I've been carrying a 3 burner coleman and will now be using dual single butane stoves (for things like spaghetti and sauce).
Cold sandwiches are great for lunch- especially on the road so you don't have to bust out the cooking gear.
Otherwise we do pretty much everything we do at home, which actually includes cold sandwiches for lunch as a regular thing. Simple is best- like I said most meals are one skillet, or one pot, but occasionally we have the vegetarian equivalent of turkey in the skillet, mashed potatoes (from a box) and green beans, which taxes my cooking equipment in both the stove and pot categories.
But usually it's one pot- like for breakfast I'll slice pre-made biscuits (gluten free of course for me..) and heat them in the skillet, get them golden brown and hot then remove them, lay cheese on them and then scramble some eggs in the same already hot skillet. Put it all together and volia biscuit sandwich. If I ate meat I'd add sausage or canadian bacon and cook it next to the biscuits and then the eggs, so it gets fully cooked but it's all still one skillet.
Very little of my food lends itself to campfire cooking, but throwing some baked potatoes in coals for an hour or using a camp grill to cook burgers, steaks or even chicken I would think would be a nice respite from dishes.
Simple stuff, and mostly done without recipies but since you asked:
Serves two:
2 Tofu Pups gluten free vegetarian hot dogs shaped food substitute
2 hot dog sticks (double stick can be substutited)
2 Gluten Free hot dog buns
2 slices cheese
ketchup
mustard
fire
Place hotdogs on stick and rotate over fire until blackened beyond recognition. Bonus points for catching them on fire like a marshmallow.
Place slice of cheese in open bun and use like a hotpad to remove dog from stick.
Cover in ketchup and mustard to try to mask the burnt flavor.
Enjoy!
