Toast the Walnuts: Place a small, dry skillet over medium heat. Add the chopped walnuts and toast for 3 to 4 minutes, stirring continuously until fragrant and lightly browned. Remove immediately from the pan to cool.
Whisk the Dressing: In a small glass jar or bowl, combine the extra-virgin olive oil, apple cider vinegar, pure honey, Dijon mustard, salt, and black pepper. Whisk vigorously or shake until completely emulsified.
Assemble the Salad: Arrange a clean bed of fresh baby spinach in a shallow serving bowl. Lay out the thin apple slices in elegant, overlapping fan shapes around the sides. Distribute the toasted walnuts, dried cranberries, and crumbled goat cheese evenly over the center.
Dress and Serve: Just before serving, drizzle the homemade vinaigrette evenly across the salad. Toss very gently. Finish with a light, artistic drizzle of pure honey over the apple slices and cheese for a gorgeous, glossy presentation.
