Creating this delicious Warm Beet and Goat Cheese Salad with Arugula and Walnuts involves a few simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Beets: Wrap the beets in aluminum foil, drizzle with a little olive oil, and sprinkle with salt and pepper.
3. Roast the Beets: Place the wrapped beets in the oven and roast for 25-30 minutes, or until they are tender when pierced with a fork.
4. Toast Walnuts: In a dry skillet over medium heat, toast the walnuts for about 5-7 minutes, stirring occasionally until fragrant. Be careful not to burn them.
5. Cool and Peel Beets: Once the beets are cooked, remove them from the oven and allow them to cool slightly. Peel the skin off; it should come off easily.
6. Slice the Beets: Cut the roasted beets into wedges or slices.
7. Prepare Dressing: In a small bowl, whisk together the olive oil and balsamic vinegar. Season with salt and pepper to taste.
8. Combine Ingredients: In a large salad bowl, toss together the arugula, warm beet slices, crumbled goat cheese, and toasted walnuts.
9. Dress the Salad: Drizzle the dressing over the salad and gently toss to combine all ingredients well.
10. Serve Immediately: The salad is best served warm, allowing the goat cheese to soften slightly against the warm beets.
