   500+ recipies used by school institutions that have a nutirion
   label and show the cost per serving and cost per recipe. They're
   all very simple recipies - easy to make in bulk, and you know
   what the nutrition is. One caveat is that the cost per
   serving/recipe data is from 2001 so you have to check your local
   prices to compare.^
