For more fiber, vitamins and minerals add ground flaxseed or wheat germ to any baked dish or casseroles. I do this to all my baked goodies and even to sauces like spaghetti sauce or to smoothies. Wheat germ is a natural source of vitamin E and Folic Acid. 1tbsp of ground flaxseed packs in a whopping 8grams of fiber!
I buy Bob's Red Mill products in the organic refrigerator section at the grocery store.
