Staling is a transformation in the starch molecules that is reversed by heat.
A good way to freshen up stale bread without toasting it is to steam it.
If it doesn't need moisture, a few seconds in the microwave oven does the job.
My favorite method: spritz with water on both sides. A few seconds in the microwave. Then a minute or two in the toaster. Even very stale bread is as good as new.
