30 meals for $3 per serving

Hy-Vee, my favorite grocery store in this area, has a new section on their website - 30 Meals for $3 per Serving. It includes recipes, shopping lists, and nutritional information for most of the main dishes. Here is one example:

Even if you don't have a Hy-Vee nearby, I'm sure these recipes could be equally affordable using ingredients from your favorite local grocery store. What are your favorite low cost dinner ideas?
