Smoothies are easy to make, nutritious, and very inexpensive. A great way also to get vital nutrition in a quickie way and a wonderful substitute for breakfast, lunch or as a snack. Here is a list of some good recipes I found on Abs Diet Online.
Recipes call for whey protein powder, but you can substitute any protein powder you may have on hand. This is available anywhere in a large can and is inexpensive.
Ground flaxseed can either be purchased in a box or container (even WalMart sells this) or you can buy in bulk at your local health food store for a very low price - just keep in your refrigerator so it does not go bad.
For the fruit smoothies, you can substitute frozen fruit instead of fresh thereby eliminating the need for ice cubes.
All recipes take 3 minutes to prepare and make 2 servings.
