Serve the salad by combining the arugula and baby spinach together in a bowl then drizzle with the well-whisked vinaigrette, to taste. Toss to coat evenly. Top the salad with the marinated beet slices, fried goat cheese coins, sliced red onion, dried cranberries, and candied pecans. Season with freshly cracked black pepper, to taste. Serve immediately. Enjoy.
