Until now I've steered clear of any kind of protein/energy/etc. bar (i.e. Luna bars, Fiber One, etc.), but I've realized that I'm on the go so often that they might actually be good as a healthy and portable snack. I had tried a few different brands in the past and remember not liking the taste very much, though, and some of them were shockingly high in calories.
So, which bars do you use? What brands taste the best and/or are the healthiest options?
