This recipe is dedicated to my dear friend Kevin, who has always loved Caesar salad, and like me, has a healthy obsession with kale. Like other dark leafy greens, kale is unbelievably nutritious, full of antioxidants. It is unusually high in fiber, vitamin A, and calcium. This salad features raw kale in a very robust Caesar dressing. Unlike romaine, kale actually benefits if it wilts slightly in the dressing. Letting it sit for 5 or ten minutes tenderizes the greens and allows the flavors to meld. The homemade croutons, sprinkled with herbes de Provence, are an excellent garnish to soak up the tasty dressing.
