I buy Zone Perfect bars - the Peanut Butter are my favorite, the Fudge Graham are great too. They are a great meal replacement or hold over until you can get a meal. The Apple Cinnamon are good too, and don't have chocolate or anything on them so they keep well in the car. I buy boxes of 6 at Target for less than $5. My kids love them, DH does too and he is really picky.
