Oats
Here’s one you probably know about already, but you may not be aware of some of the less conventional forms and uses for this soluble fiber-rich grain. While oatmeal is an obvious winner, oat flour is another versatile option. If you can’t find it in the places you typically shop, you can make your own by pulverizing rolled oats in a food processor. Oat flour can be substituted for up to half the all-purpose flour in most pancake and muffin recipes; I even use it in the low-fat oatmeal cookies my kids adore.
