$7 per 60 eggs (5 dozen) is approx. $2.33 per daily caloric budget, (per this, http://caloriecount.about.com/calories-egg-whole-i1130 assuming you do omelet) which is not incredible, but maybe acceptable deal, given this extreme budgetary constraints.

I, personally, consider eggs reasonably cheap, healthy and fast food, but I did not try to live on $3/$1 per day. (still havent' figured if I should worry about cholesterol)
