Once, someone made me a Kale Sandwhich. It used Kale leaves as the bread. Broiled in the oven. Krispy. melted cheese. Ham. It was strangely edible, once I got the Kale out from being stuck to the roof of my mouth, peeled it out and threw it away. I started coughing like a cat with a hairball. Still, the ham and cheese was good.
