I've never even heard of the things.
I hate 'granola bars' of all stripes; they're nutritionally lacking and way too expensive for what you get. Just eat the wrapper if you need the fiber or have a bowl of oatmeal, LOL! Pop a vitamin pill if you're not able to eat a balanced diet that day for whatever reason.
Let's talk about homemade GORP! Now THAT'S worth eating. Nuts, dried fruits, a little unsweetened flake coconut and M&Ms. Nature's Most Perfect Snack, IMHO. I consider M&Ms part of MY balanced diet, LOL!
I will eat granola on yogurt once in a great while for crunch, but mainly it makes me want to gag because I associate it with being 'Hippy Food,' eventhough I am pretty much a 'Crunchy Conservative' myself. :)
