Fresh kale is mine, and I did the easiest, tastiest thing I could think of: kale chips.
My kale comes washed and cut into bite-size pieces. All I have to do is give a final rinse (more for my sanity than for the sanitation of the kale), toss in a ziploc bag with some olive oil, scatter them in a thin layer on a baking sheet and bake at 150 °C for about 20 minutes. Toss with salt and nutritional yeast, put on a movie and you'll not miss chips.
If there are any, I keep leftover kale chips in a ziploc bag filled with air (my own recreation of a potato chip bag), and toast them before I devour another bowl.
Nutritional yeast is the secret umami I've stolen from the hands of vegans. Apparently it contains B-vitamins. It also contains a whole lot of flavour and can be used to flavour soups, and, oh so importantly, snacks like popcorn and kale chips.
