Leanne Brown has authored a free e-book cook book for people who are living on food stamps.  The book is titled Eat Well on $4 a Day, Good and Cheap.

She is a food scholar that is doing this to give to the community.  The cook book started as a project in college.  She lives in New York City so the recipes have lots of ethnic flair to them. It is a small cook book.   

Eating well on a limited income and keeping a family full and healthy can be done. But you have to learn how to cook with basic ingredients.  There is a learning curve and a cook book like this makes it a little easier to adapt to a low income. She has also kept in mind that most on food stamps don't have a fully equipped kitchen. I am glad that some one besides me understands that it is cooking skills that can see you through difficult budget weeks. There are some very nice suggestions when you are out of money and out of ideas.  

PS.  She is offering a second free cookbook that has some wonderful vegetarian dishes in it. Good cooking tips for vegetables.
