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 the North East to where there are 15-20 Radscorpions that re-spawn after you wait three days, kill them and loot them to get their glands. Take the glands to Ruby Nash in Primm and she will turn them into Ruby's casserole 5 at a time, eat all the "casserole" at once(if doing the casserole method you need to have lost HP equal to or greater than the amount of health that will be gained from one) with a survival skill of 100 only require 112 casseroles (+3HP(30s) each). This will work for other food items by eating many of the same item at once and having lost HP greater than the amount gained by one, however, Ruby's casserole is a very effective and easy to acquire food item. This works because the game counts the amount of health gained from food before you begin healing so as long as you have enough damage to use all the healing of one "casseroles" it will consider the amount that you healed as all of "casseroles" (i.e. if you gain +1(30s)HP and eat 40 it will record the amount healed by food as increasing by 1200 however if you only have 20 damage to heal the amount healed by food will only increase by 800)
