I warmed them in a pan with olive oil, on low heat at first, then I turned up the heat to help the roots get their crispy on. A big bowl of kale was then dumped on top and I tossed the whole panful with two wooden spoons for about 3 minutes. The resulting "breakfast hash" was just what I wanted.
In other news, after a recent juicing mishap, I noticed veggies on the ceiling. I fetched the ladder and did what I could to eradicate the mess, but it looks like there'll be a permanent stain. I got a good belly laugh from my 16 year old though -- any little thing I can do to entertain that sweet girl, who revels in my veggie adventures.
