Desert Survivalist

 is an achievement in Fallout: New Vegas which is awarded for successfully healing 10,000 points of damage using food.

The easiest way to get this is to go to Goodsprings Cemetery and go down the hill to where there are 15-20 Radscorpions that re-spawn around every 3 days, kill them and loot them to get their glands. Take the glands to Ruby Nash in Primme and she will turn them into casserole, eat the casserole (you don't actually need to be hurt to get the trophy/achievement) with a high enough amount of survival skill this will take about 30 minutes and need only about 120 casseroles
