What the hell do I do with this vegetable: kale and sweet potato edition

Fair Foods has had a lot of kale recently. This past week they had kale and sweet potatoes. I figured I'd do some experimentation, and hey, it's soup weather, right? First, I cooked it up in the slow cooker with a little water until done. Then I proceeded to make some different soups with stuff I had on hand.

Shown here: kale and sweet potatoes in slow cooker

First up: simmered it with some milk, muenster cheese, white potatoes, salt and pepper. Used immersion blender to puree it about halfway.

Next: simmered it with some red potatoes, dill, soy sausage, onions, salt and pepper

Added kidney beans and black beans, diced tomatoes, tomato paste, onions, garlic, chili seasoning. I cooked it down a bit longer than shown here.

Finally, since I still had some left, I tossed it in with some eggs and cheese and made a frittata for breakfast the next morning. Everything I made was gone quite fast, and I would make it all again.
