I've been making veggie chips using this method for a long time, but Heather Crosby at YumUniverse put together an awesome video tutorial for kale chips. Check it out here. The almond flour (you can also use almond meal, available at Trader Joe's) makes the kale chips taste almost breaded and deep fried- they taste completely unhealthy, but are absolutely the opposite. I've used the same idea to make zucchini and spinach chips in the food dehydrator with great success.
When Tye was newer to solids, I made sure the chips she ate were really crunchy and crumbly and it was an easy way to incorporate otherwise stringy, chewy leafy greens into her diet. Now when I pull a batch of kale chips out of the oven, Tye gasps with delight and barely waits for them to cool before stuffing them in her mouth. They're a salty, delicious snack to feel really good about.
