I've toasted bread in a frying pan, too. It works though its not as toasty, not as dried. Definitely fried, not crispy thru & thru. But hey, I've pan fried many a piece of toast in my day.
So here's the tin can idea. Take one big jumbo can? Cut off both ends.
Use something to support a slice of bread --- mesh, grill, couple of chop sticks or skewers, etc. Set the can atop the woodstove. Add a slice of bread.
Then watch it closely until crispy on one side. Flip it over and toast the other side. Only takes a few minutes. I gave this thing a trial run this morning (it was 52 degrees in my house the morning I did this...brrr). Works great. In fact, I made myself another piece and put farm fresh honey on it. Yum!
