Simple, cheap, yet delicious :-)

A quick google search and I found this: https://www.tastemade.com/videos/campfire-bread-on-a-stick

We use much thinner sticks, we use yeast rather than baking powder, and we eat the bread as it is, without any fancy topping. Of course, when the kids make it it will often be burnt on the outside and doughy inside - best to supervise a bit, and also to put as thin layer of dough as possible around the stick to make sure it will be ready before the kids get too impatient.
