Iguana-on-a-stick

Iguana-on-a-stick, available as a whole iguana or in the form of iguana bits, is an edible food item in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas and Fallout Tactics to replenish hit points.

Fallout 3
Named iguana on a stick in Fallout 3, the item is commonly found throughout the Capital Wasteland, both in containers or being sold by vendors. Although the item itself is common, live iguanas are not seen anywhere in the Capital Wasteland

Fallout: New Vegas
Iguana on a stick is semi-commonly found in containers throughout the area. It provides more than double the amount of health compared to its Fallout 3 counterpart, though this is still a fairly small amount. Within Hardcore mode the item is more useful, providing a large restoration to the Courier's Starvation level at a relatively low cost, weight, and difficulty to obtain.

As in the Capital Wasteland, no live iguanas are found anywhere in the Mojave.
