Kale "sauerkraut"

I've been loving my sister's new barbarian cooks blog with fun ideas for kale. But when I was ultra-lazy, pressed for time, and eating solo for dinner one night last week, I came up with another fun thing to do with that huge bag o' greens: sauteed a big pile of those suckers in a pan, added a splash of vinegar, a splash of water, and spoonful of mustard. I let it cook down all soft and smooshy while I microwaved a Trader Joe's Italian vegetarian sausage and toasted a tasty hot dog roll from my neighborhood butcher, A & J Meats*. I put it all together, and it tasted DELICIOUS!

*I walk by this wonderful butcher pretty much any time I'm going anywhere. Everyone who works there is informative, helpful, and kind. I keep going in just to buy hot dog rolls and mustard. I feel like I have to explain myself somehow... Would it be weird if I told our butcher I'm vegan? I feel guilty that I'm not giving this local, family business as much money anymore. They are really good people! And they have great meats for all you Seattle-area omnivores!
