Chard and kale in a lemony vinaigrette and topped with walnuts and feta cubes. I like to use the feta cubes you can buy seasoned with herbs and olive oil.
Combine chard and kale in a large salad bowl. Add lemon juice, olive oil and salt and pepper to taste. Using both hands gently massage the leaves for a minute or so. Leaves should soften, but do not crush.
Top the salad with walnuts and feta cubes, then serve.
