Campfire cooking gone wrong

Took the kids camping in upstate NY and thought I'd be all outdoorsy and cook everything over the fire. Note to self: foil packet meals sound good in theory but are impossible to cook evenly and my 8yo got cold waiting for dinner to be ready. We ended up eating at like 8:30pm which was a whole thing. Next time I'm bringing a camp stove. Anyone else just accept that camping cooking is hard or am I missing something obvious?
