Preheat your oven to 350°F. Spread out the sliced almonds on a baking sheet and toast until fragrant, about 4 to 6 minutes.
In a medium bowl, combine baby spinach, mandarin oranges, red onion, goat cheese, sliced almonds, and dried cranberries. Toss gently to mix.
Prepare the dressing by whisking together olive oil, balsamic vinegar, honey, and Dijon mustard. Adjust with salt and pepper as desired.
Pour the dressing over the salad mixture and toss just before serving to keep the spinach fresh.
Serve immediately and enjoy the burst of flavors!
