Yeah, kale chips are are actually really tasty. They smell disgusting while cooking, but they taste terrific and are quite addicting. All the kids like them (or at least those that have tried them.) I found my four year old walking upstairs with a handful of them - after I'd put him to bed! My 10 year old had been begging me to make them but I'd dreaded it because the recipe I had used previously was a bit work-intensive. This is the simple way to make them.
1 bunch kale
olive oil, sprayer or liquid
1/8 cup shredded parmesan (optional)
Preheat oven to 375. Wash and thoroughly dry the kale. Prep a cookie sheet by lining it with parchment paper (or tin foil.) Rip the kale from the thick stem into 2" pieces (or so, obviously this won't come out perfect, but as you rip it from the thick stem, you'll see what I mean. Put those pieces on the cookie sheet. When done ripping, spread out the kale evenly. Spray with olive oil or drizzle thin stream of olive oil onto the kale, then sprinkle with salt. Toss with your hands and spread out evenly again. Repeat 1 or 2 more times until it is to your liking. The last time, sprinkle parmesan and toss. Don't worry if some of the parmesan falls to the bottom of the pan, it'll still stick to the kale.
Bake for 10 minutes, then keep checking it every minute until kale is crispy, but not brown and burnt! Every oven is different, so this is the hardest part about it.
Store in a bowl or plastic bag, but it might all get eaten first.
