Mole rat meat

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

Fallout 3
It can be mixed with Wonderglue in the meat-proccessor found in Jury Street Metro Station to make Mole Rat Wonder Meat, which is significantly better than the standard meat.

Fallout: New Vegas
It's an ingredient in the Mole rat stew made at campfires. Using it in this recipe removes the rads you would get from raw meat.
