i love kale many ways: chips, sauteed, in soups, etc. this is my new favorite:

and you can several different kinds and it still works great.

I like it in a pasta with lots of garlic and Italian Sausage (http://www.asageamalgam.com/2011/02/kale-and-sausage-pasta.html) and in bean soup (http://www.asageamalgam.com/2011/03/bean-and-bacon-soup.html).

Super simple: steam it with a three-fingered pinch of salt.

one of my favorites for Kale, it's fresh and super easy!!

It depends on what type of kale you have. Tuscan/dinosaur kale - I like them for kale chips and saute. The green, kind of curly type kale - I like them in soup or cook them like I would with collard greens. Russian red - saute with garlic, onion and cured pork products (bacon, speck, pancetta, etc.). Flowering kale - soup or saute.

i should add--this is a side dish i often make with pork tenderloin or simple grilled chicken breasts.

the simplest method: blanche kale for 8 minutes until leaves become a bit tender. drain; sautee a tsp or two of minced garlic in 1 or 2 tbsp olive oil for a minute, add a sprinkle of hot chili falkes, add the kale and saute until hot and combined. yum! sorry to be imprecise--i don't measure this one, but it's pretty hard to mess it up.

Here's another lovely food52 recipe for kale:

If you eat bacon: Render several slices of bacon in a large heavy pan. When crisp, drain on paper towels. Wipe out the pan w/ papertowels. Add 1 to 2 tbs olive oil & a big pinch of crushed red pepper, heat over medium high heat.
Wash & tear 1 bunch of kale into bite-sized pieces. Toss into the hot pan. Stir often. Once wilted, taste for doneness. Crumble the crisp bacon over the top when ready to serve. You can also add in some thinly sliced garlic w/ the red pepper if you like.

Kale salad is a favorite of mine, and Mark Bittman has a great recipe http://www.nytimes.com/2011/06/19/magazine/bold-salads.html?_r=1&hpw&gwh=D53C521D0E3C87B4274F4D7FD61CEFF5 And here is a great web site that is all about kale. http://www.365daysofkale.com/2009/03/how-should-i-eat-my-kale-raw-or-cooked.html

kale chips are my newest addiction. tear kate into pieces, drench in olive oil, salt and pepper. bake in 1 layer on a baking sheet in 350 oven for 10-15 mins. heidi swanson does an awesome salad in her new book. she adds soy sauce/a tiny amount of toasted sesame oil to the oil and then sprinkles dessicated coconut. that is crazy good!

Here's a wonderful recipe for kale:

You can make Colcannon, an Irish dish with mashed potatoes and kale (recipes readily available via google) or shred the kale and dress it with a vinaigrette, then leave it for a bit to soften the leaves. Toss with pomegranate seeds and toasted pine nuts, throw in some feta, it's a great salad.

I like to crush a 3-4 garlic cloves, then warm them over low heat in about 1/4 cup olive oil for about 5 minutes with a pinch of red pepper flakes. Fish out the cloves, turn up the heat to medium, and add the kale. Cook for about 15-20 minutes, then remove from heat. Stir in about 1/4 tsp. toasted sesame oil and 2 teaspoons soy sauce (or more to your taste). Salt, pepper, eat.

Caldo Verde (Portuguese Soup) is quite delicious. Put a couple of Tbsp olive oil in a pan, add a couple cloves garlic, 2 bay leave and a sprinkle of hot red pepper flakes. Let the oil sizzle a minute and add a chopped onion. After onion softens, 8 minutes, add 2 or 3 chopped potatoes, chopped bunch of kale (inside rib removed, and chicken stock or water (I like to use 1/2 and 1/2) to cover. Simmer until tender, about 30 minutes. Add sliced smoked sausage and heat. Use linguica, smoked chorizo or even smoked chicken or turkey sausage.

If you google, you'll find many recipe and variations of this famous dish.
