One of my greatest successes as a father of twin boy toddlers came recently with their intense yelling for "MORE KALE!!!!"
Based on their love of anything crispy or crunchy, I decided to try a crispy roast kale recipe on them. I picked up your standard curly kale from the farmers market, de-ribbed and cut the leaves, lightly tossed with oil and roasted at 375 for about 12 mins, turning once. Garnished with a bit of sea salt and a splash of vinegar, these are as good as any potato chip.
My boys are not overly picky eaters (yet), but I have found that if you pretend that a food item is not for them, they're all the more likely to hunger for it. If broccoli is on their plate, they'll mostly ignore it until they see me start eating it too.
So, when the first batch of kale was ready, I stood at the counter and crunched on a couple while ignoring them.
Within seconds the cries of "CRUNCHY!" "CHIPS!" "WANT SOME CHIPS!" "HAVE SOME PLEASE!" started.
"Oh, you want to taste some kale?"
"YES! KALE! PLEASE! CRUNCHY! WANT SOME!"
Roasted kale chips are now the snack of the month. On the plus side, I've read that they retain a good percentage of their nutritional value when cooked this way. (Frankly, even if they retain only 10% of their nutritonal value, it's a win since you're not gonna get any sane person to eat very much raw kale.)
