Roasted Beet Goat Cheese Salad

Preheat oven to 400°. Wrap each beet in foil and place on a baking sheet. Roast until tender (you can insert a fork or knife through the foil to test), about 1 hour. Let sit until cool enough to handle, then peel and cut into wedges. Place arugula in a large serving bowl and lightly dress with vinaigrette. Top with beets, avocado, goat cheese, and walnuts. Toss gently and add more vinaigrette as needed.
