I usually avoid recipes that call for the addition of cans of Cream of Something soup because I don't like all the salt & other unpronounceable ingredients they contain. But can I substitute a basic White Sauce for those cans of cream soup, adding other wholesome ingredients for flavor? I wanted to make a dish using bow tie pasta, cooked white meat chicken, chopped carrots & broccoli, with a creamy white sauce to hold it all together. I melted butter in a pan, added an equal amount of flour & whisked it together, then added some milk, salt & pepper, & simmered it for a few minutes until it thickened. It all came out all right, but I'd like it to be BETTER. What else could be added for flavoring? Or for color? Could olive oil be substituted for the butter? I don't mind using butter in moderation, but try to keep our meals more low-fat. And there's supposed to be special health benefits in olive oil. Would I use extra-virgin or light tasting? Is it better to use higher-percentage fat milk? We use skim and 1%. Could soy milk be used? Please include any recipes you use for a good basic White Sauce that uses healthy wholesome ingredients. Thank you!
