Sweet roasted beets, crunchy walnuts, and bright baby spinach make a simple but well-balanced salad.
Preheat oven to 425°F (220°C). Place beets on a baking sheet. Roast until fork tender, about 1 hour. When cool enough to handle, peel beets and roughly chop. If canned, roast 20 minutes.
Place spinach, beets, goat cheese, and walnuts in a large bowl.
In a small bowl, whisk together olive oil and vinegar. Whisk in salt and pepper. Pour dressing over salad and toss to combine.
