Add the kale, toss to coat and let stand 10 minutes.Step 3While the kale stands, cut the dates into thin slivers and the apple into matchsticks. Add the dates, apples, cheese and almonds to the kale. Season with pepper, toss well and set aside.Step 4Sprinkle the salmon all over with 1/2 teaspoon salt and some pepper. Heat the remaining 1 tablespoon oil in a large nonstick skillet over medium-low heat. Raise the heat to medium-high. Place the salmon, skin-side up in the pan. Cook until golden brown on one side, about 4 minutes. Turn the fish over with a spatula, and cook until it feels firm to the touch, about 3 minutes more.Step 5Divide the salmon, salad and rolls evenly among four plates.
