Make the vinaigrette. Combine all of the vinaigrette ingredients together in a bowl and whisk vigorously (or shake them together in a mason jar) to combine.
Toss the salad. Add spinach, apples, red onion, walnuts, dried cranberries, and half of the goat cheese to a large bowl. Drizzle with the vinaigrette, and toss to combine.
Serve. Serve immediately, garnished with the remaining goat cheese, and enjoy!
