Beet Salad with Maple Mustard Vinaigrette

Poor, poor, unposted salad blog post. I have had this box of pre-cooked beets in my fridge for months, waiting for me to remember to buy the other ingredients that make a good beet salad. I can never remember to get the perfect nuts or cheese. I finally put it together last week, TWICE, but never got to post it. I've made this many different ways before, but I found a new dressing recipe that is sooooo good. The salad is simply: baby spinach, sliced cooked beets, toasted pistacios, and shaved fresh parmigiano cheese. The dressing I used was a Maple-Mustard Vinaigrette from foodnetwork.com.
