I am a big fan of KIND bars. I normally don't like a lot of the gross powerbar type things but these nut bars are great. You have to pay attention to the calories because some of them are different. My favorite is the fruit and nut delight. I have seen them at both HEB and AREI (by the way has a great selection on these types of food for a better price!) Here is their website to buy in bulk
