When I was a Camp Fire Girl, I was quite impressed when we made our own individual camp cook stoves. I won't admit how many years ago that was, but the camp project has stuck with me all these years.
There are two main parts to the cook stove. There's the buddy burner or heat source, and then the actual stove, which was a one-gallon coffee can. You get the picture.
When I was thinking about how to stretch the two pieces of bread I had left in the loaf this morning, I remembered the old toad-in-a-hole we made on those coffee-can stoves.
You cut a hole about two-inches around in the center of your piece of bread, then butter the bread frame. Place it on top of the camp stove top (or frying pan, if you're in the kitchen). Break an egg into the bread hole. Add salt and pepper.
Let cook and flip to brown the other side.
Tah dah! Being creative is the mother of invention.
