"The snack that Dunn was proposing to sell: carrots. Plain, fresh carrots. No added sugar. No creamy sauce or dips. No salt. Just baby carrots, washed, bagged, then sold into the deadly dull produce aisle."
Ha, I've actually been doing this since I was a teenager. It's really fantastic for managing junk food cravings, which arise not because I'm hungry, but because I just like to have something to chew on while I work (especially while programming). A one-pound bag lasts me about three hours and is more-or-less guilt-free.
