Toasty biscuit
put a bit of olive oil on a piece of frozen bread. Normal unfrozen bread is OK but the oil then soaks in too quickly - it just sits on top of the frozen slice. Microwave on high for just under 2 minutes (trial & error here - too long and you'll burn it, but it must be long enough for the bread to get crisp and hard)
You end up with a great tasty biscuit, of sorts ..
