Here's another approach to grilled kale - call it the fifteen minute, two ingredient version. Ronan's grilled kale is a better recipe if you ate preparing this dish for guests and this is the version I do when I just need something quick.
Chop the kale into large bite-sized pieces. Toss with about a quarter cup of olive oil and plenty of salt. Place chopped kale in a deep grill basket and grill on medium heat with top closed. Shake and turn every five minutes until the leaves are wilted, about 10-15 minutes in total. Place kale on platter and add olive oil if the kale looks dry. Serve with sliced plums.
Also works well with peaches, nectarines and strawberries.
