Strange meat

 is a food item found in Fallout 3. It can restore some of your Hit Points, but also gives you a small amount of radiation. Considering that you can only buy or loot it from hunters, who are often seen "hunting" lone wastelanders, and the hunters' jokes that it could be "sweetest thing you'll ever eat," this meat is most likely human meat.

A large supply of strange meat (60+) can be stolen in Andale. You can also receive a free Strange Meat Pie daily from Linda Smith.

Strange Meat can be traded to Eclair in Little Lamplight in exchange for Cave Fungus.

Strange Meat may be a reference to fake Iguana-on-a-stick from Fallout 1. It could also be a rather far-flung reference to Soylent Green, as one does not know what exactly it is made of right away, and both are shockingly made out of the same ingredient: people.

 * At one point my character became addicted to strange meat, it had no adverse or positive effects.
