The Slow Food Movement has had people blogging on their website about how they accomplished the $5 meal challenge.
Please check out their page for sharing recipe ideas (and pictures) here: http://5challenge.tumblr.com/ and let your own creativity about meal planning grow and prosper. When I looked a little further for $5 meals I came across the $5 dinner website that is chock full of ideas about meals to cook on the cheap and easy. http://www.5dollardinners.com/recipes
Eating cheap, fast, easy and healthy is definitely doable! To increase your pleasure, invite some friends over and make it fun.
