You can also make kale chips. They are crunchy like chips but hardly any calories, and you can use the oven so no special equipment needed. Below is the recipe I follow, but I don't have a salad spinner so I use a paper towel to dry the kale, and I put the kale in a bowl and toss with the oil.
1. Preheat an oven to 350 degrees F (175 degrees C). Line a non insulated cookie sheet with parchment paper.
2.With a knife or kitchen shears carefully remove the leaves from the thick stems and tear into bite size pieces. Wash and thoroughly dry kale with a salad spinner. Drizzle kale with olive oil and sprinkle with seasoning salt.
3.Bake until the edges brown but are not burnt, 10 to 15 minutes.
I think they will keep in a container or zip lock for a few days, but my kids eat them so fast I have never gotten to find out.
