Correct on the oats. I grind a 1/2 cup in a coffee bean grinder and mix it in my PW shake.
I have some PowerBars that I eat only if there's nothing else, or if I need something quick after my workout and a shake is not in the cards. I bought a case several months ago, and still have some left, so it's rare that I eat them. I actually like the regular Powerbars, chocolate, peanut butter, and vanilla crisp all taste good, just not the best thing for you.
