In my area 3-1 lb. boxes of pasta are on sale for $1.00. even at $0.88 a box, 1 box will feed a family of 4-5 with no problem. I can eat 1/2 of a 1 lb. bag of veggies by myself. And if you're not feeding carbs, you need to fill the stomach with more meat and veggies.

Now buying junk is another issue, true without junk you can expand your budget for meat and veggies but lets not fool ourselves carbs are cheap. And they taste good. A bottom line buget issue for schools and some families.
