Kale is in my top favorite of vegetables!
I use the entire bunch of kale, not discarding a thing!
I like it in soup (especially with potato, onion, leek, garlic...MMMM!), steamed and tossed with garlic, lemon and a good oil with a pinch of salt and pepper...it's good cooked like that served on top of mashed potatoes
...Kale chips are good too (baked after seasoning, so good!).
