Gold Powder
When Moses sees the Israelites worshiping the golden calf he grinds the idol into a fine powder, mixes it with water and forces the people to drink (Exodus 32:1920).
Scroll of Lamentations
God gives Ezekiel a two-sided scroll of Lamentations to eat. Ezekiel fills his stomach and finds the scroll to be as sweet as honey (Ezekiel 2:83:3).
Bread and Excrement
God tells Ezekiel to eat bread baked upon human excrement but Ezekiel gets away with bread baked upon animal excrement. Unlike the scroll, we arent told how it tastes (Ezekiel 4:10-17).
Human Flesh
Cannibalism on account of hunger is perhaps the most extreme punishment in the Hebrew Bible. It is at times described in vivid detail, e.g., in the threat of Deuteronomy 28 that fathers and mothers will eat their own children in secrecy so that they do not have to share the meat (Deuteronomy 28:5357).
Free Refills
There are a number of stories about the miracles performed by the prophets Elijah and Elisha. According to the Book of Kings, a hungry womans jar of flour and jug of oil refilled themselves until a famine subsided (1 Kings 17:10-16), a poor womans single jug of oil was able to fill the many vessels of her neighbors (2 Kings 4:17), and a mans twenty loaves of bread were miraculously able to feed one hundred hungry men with some left over (2 Kings 4:4244). A similar story appears in John 6, where Jesus feeds five thousand men with five barley loaves and two small fish. Again, there is still food left over.
