EWG has put together this really great site to educate anyone about the fruits, veggies, grains, proteins, dairy, etc. that pack the most nutrition into your diet and stretch the most out of your budget.
You can browse the website and even download a handy printable shopping guide that provides a cheat sheet of foods to buy, budgeting tools and a meal planning worksheet. Get the guide here. [link to http://static.ewg.org/reports/2012/goodfood/pdf/goodfoodonatightbudget.pdf]
