Bread Spawn Meat (3.5e Equipment)
From D&D Wiki
The meat of a bread spawn will sustain a creature for a whole day. This meat also channels positive energy into the body of the creature who eats it, which cures 1d8 points of damage +1 point per HD of the bread spawn (maximum +5).
One bread spawn's meat will sustain a creature for a whole day, the creature need not eat anything else but still must drink and sleep.
