My sister and I love kale. She grew the most beautiful hydroponic greens in Hawaii, and we enjoyed it daily, lightly sautéd in olive oil and garlic. She told me about this six-ingredient kale salad that she discovered on the Epicurious website. We made it last week, and it is delicious. Unlike other dressed salads, this one holds up well in the refrigerator to enjoy the next day. —KIM B. MCKINNEY…
