Have a taste for something sweet? Make sure you pick up some peanut butter. You can make a simple peanut butter bread snack, or peanut butter and jelly if you have the latter. You can also put some on a piece of apple, on banana, crackers, or pretzels. Get real jazzy and throw it in a fruity smoothie or blend it into an almond milkshake. If your favorite junk food is a no for you, peanut butter is a perfect substitute.
