Most people don't like Kale. They probably don't like Spinnich either. I like both. I steam them in a med/large pot (with a cover) with a layer of "chicken broth" and other spices like garlic and dill in the pot.
Bring the broth up to a near boil and add the Kale/Spinnach and steam for NO More than
3 minutes. When done..bail the veg out with Tongs into a serving bowl.
THIS is the key: Splash of
Balsamic Vinegar on the serving bowl of veg ..On The table. ..Just prior to serving.

NB
