Fresh potato

 is a food item found in Fallout 3. It can restore some of your Hit Points, without giving any radiation.


 * One can be found in Pinkerton's Lab, in the broken bow of Rivet City.
 * Ten are in the Science Lab in Rivet City, though taking them is a crime. Dogmeat can get them for you with no karma penalty. (PC, PS3, but not Xbox?)
 * Note that the scientists gather up the fresh fruit over time, if you wait (manually, not using Wait).
