I agree with others that GF bread in general tastes better & has a nicer consistency when warmed up... does not have to be toasted, just warmed.
I take a few days supply of bread & bagels out of the freezer at a time and place it in the fridge to thaw. Then when ready to eat, it is just a quick warm-up in the toaster. This also allows my son to make his own lunchbox sandwiches independently (young teen) because he is allowed to use the toaster without supervision - but not the oven or microwave.
For the hamburger & hot dog buns, I usually leave those in the freezer... When needed, I wrap an individual bun in a paper towel and put it in the microwave on defrost mode. The paper towel keeps the moisture in nicely as it warms... or if you want it even moister, mist/sprinkle the paper towel with water before putting it in the microwave.
