I'll make more next time. I asked at the health food store if it would reduce in size and she insisted it wouldn't. So I cut about 6 or 7 large leaves into strips (about a third of the bunch), washed, spun, tossed with OO and roasted at the 250 temp for 35 minutes. The pieces lightly covered a large cookie sheet, but then completely collapsed to thin pieces. Ended up with one (I call them French cafe au lait) bowls of chips out of it. Tasty, but for the time, I'd make ALL of the kale at the same time. It was the dark, ruffly stuff, might be Lacinato (definitely different from the precut bag of kale at the grocery store.)
