Add ¼ cup brown sugar, ¼ cup apple cider vinegar, and ¼ cup extra virgin olive oil into a mason jar and shake until completely combined. Set aside.
Build the salad in layers, first with 4 cups spinach or arugula, then 1 cup chopped roasted or canned beets, ¼ cup thinly sliced red onion, ⅓ cup candied pecans and ¼ cup crumbled goat cheese.
Drizzle the vinaigrette over the salad and serve.
Notes
Make ahead:
This salad can be prepared in advance but is best assembled just before serving.
