Mix the Dressing: Combine the apple cider vinegar, maple syrup, Dijon mustard, minced garlic, olive oil, salt, and pepper in a small mixing bowl or a resealable jar. Whisk or shake the ingredients together until fully blended and emulsified. Set the dressing aside, and stir or shake it again if it separates before use.
Toast the Nuts: Place a small dry skillet over medium heat and add the pecans or almonds. Stir them frequently for 2 to 3 minutes, until they become fragrant and develop a golden color. Immediately transfer the nuts to a plate to cool, as they can burn quickly if left in the pan.
Prepare the Kale: Remove the kale leaves from their stems and discard the stems. Rinse the leaves under cold running water, then dry them thoroughly using a salad spinner or a clean kitchen towel. Stack several leaves together, slice them into thin strips, and place the chopped kale in a large bowl.
Dress the Kale: Pour about three-quarters of the prepared dressing over the kale. Use two forks to gently toss and massage the leaves for several minutes, allowing the dressing to coat them evenly and soften the kale. Let it rest for about 15 minutes to absorb the flavors.
Assemble the Salad: Add the sliced apples, toasted nuts, pomegranate seeds, and crumbled goat cheese on top of the kale. Drizzle the remaining dressing over the salad, or serve it on the side for individual portions. Toss gently before serving to combine the flavors.
