Food Networks Alton Brown has one here that looks good too. It's similar, but requires oven time whereas the one above (after toasting the base ingredients) does not.
I'll have to keep looking for the other one that I stumbled on and wanted to try.
Anyway, I've also found myself very much addicted to banana chips, but as I like to have a little more control over my food and I hate paying for preservatives, I went searching for recipe and found this. Simple, I know, but I often have to see what other people did to make it work for me.
Lastly, if you're looking for healthy snacks to make, my Living on a Dime newsletter had a link to a free 40 healthy snack recipe e-book. I found this fun and am excited to try the baked version of fried zucchini, gummy candy, and a trail mix that uses banana chips, hazelnuts, and has vanilla flavor via vanilla pudding.
Okay, no really, this one is the last thing I'll post. I really enjoy going to eatbetteramerica.com. They have lots of "healthified" foods and give you a nutritional rundown too. Gotta love that!
