I love Kale chips and Zucchini chips, but my favorite crunchy snack is a bit unusual. I take a piece of parchment paper, slice up a low fat cheese (usually just sandwich cheese) and microwave it on the paper for about 45 seconds. The cheese puffs up and gets crunchy. Sounds really bizarre, but it's very good. Just be sure you're not using a high fat cheese or it will defeat the purpose.
I've tried kale chips before and although I LOVE kale, the chips made me gag for some reason lol. I don't know what it was about them, but I couldn't eat them. I haven't checked out that link yet, but I'll save it for tonight. Thanks!
