Squirrel on a stick

 is a food item found in Fallout 3 and Fallout: New Vegas. It can restore some of your Hit Points, but also gives you a small amount of radiation.

You can easily find it in most stores in the Capital Wasteland, also some hunters or citizens will have it. The Super-Duper Mart has some too. It can also be found in Hollow logs in the Fallout: New Vegas Add-on Honest Hearts. There are no known recipes using this item, so you may eat it or sell it without worry. Oddly enough, squirrels do not appear in either Fallout 3 or Fallout: New Vegas.
