Have you taken a look at the 'Everyday' magazine by Rachel Ray? There is a section in there on meals under a certain price per serving. They are delicious and nutritious, and most are under $3 per serving. She gives the recipes, a shopping list, and tips on how to prepare dishes with leftovers. Personally, I spend less than $25 per week on food for myself if I average it out. I do all kinds of things to keep my costs down.
