If you haven't tried, you'll be surprised at how good it is. Just take some kale (god gammaldags grønnkål!),chop off the hard parts of the stem, and tear or cut it into small pieces. Spread the bite size pieces on parchment paper, salt the kale and drizzle it with xtra virgin olive oil. For extra spice I like to add some chilli as well. Bake on low heat (around 80 degress celsius/175 fahrenheit) untill the edges are slightly colored, 10 to 15 minutes. Make a lot, because once you start, you really can't stop... In that sense it's exactly the same as with potato chips!
