In small saucepan over medium heat, cook and stir the walnuts and sugar until walnuts are lightly browned and sugar is caramelized. Thoroughly coat the walnuts with the sugar.
In a blender or food processor, blend the beets with cider vinegar, bouillon granules, garlic powder, sugar, salt, and pepper. Gradually blend in the oil.
In a large bowl, toss together the sugar-coated walnuts and spinach. Before serving, drizzle with the blended beat mixture, toss, and sprinkle with goat cheese.
