You have choices when it comes to shopping for kale! If you’re using a more bitter kale, like curly kale, you may want to keep that optional step of adding citrus or apple cider vinegar and Parmesan after taking your kale out of the sauté pan.
Red kale has a similar flavor profile, but it has reddish leaves and stems. Treat it as you would curly kale.
Baby kale is tasty with other greens in a salad. It’s gentle enough to include in a spinach artichoke dip, too.
