White Sauce

I am always on a quest for less expensive, more healthy ways to cook. I recently came across this post that inspires me to use less cans of "cream-of-something" in my recipes. I would think this could really cut out sodium from many recipes. Check out the comments, too. They offer further tips.

Do you have any great tips to offer me? Any ideas you could give me for easy ways to cut cost and to cut unhealthy food out of our diet would be gratefully received.
