Remove the ribs from the kale, add to bowl or salad spinner and wash with cool water, drain and spin dry.
Cut kale into long ribbons, rolling many leaves together and cutting into ½" thick strips. Add to a large bowl.
Add freshly-squeezed lemon juice, olive oil, and salt to the kale. Massage the greens with your hands until tender and they start to release some of their juice. Should be about 3-5 minutes, taste and adjust seasoning / flavor as necessary.
