A Wasteland omelet heals 660 HP (that's not a typo), but requires a Survival of 65 and the ingredients are hard to come by - especially lakelurk meat and deathclaw eggs. Cook-Cook's Fiend stew heals 120 HP, but requires a Survival of 75 to craft. Mole rat stew heals 60 HP, but takes a Survival of 65 to craft and requires pinto bean pods which are extremly hard to find. Trail mix heals 75 HP and only requires a Survival of 25. However, the ingredients are somewhat hard to come by. Ruby's casserole heals 30 HP, and only requires a radscorpion poison gland. Remember that the items will heal different amounts depending on your Survival skill.
